The straight line distance between two cities A and B is 223 km. The straight line distance between cities A and C is 152 km. The straight line distance between cities B and C is 285 km. Find the measure of the angle when standing at city C between the lines of sight to cities A and B.
Answer:
Angle between the lines of sight to A and B = 50.94°
Step-by-step explanation:
Distance between the cities A and B = 223 km
Distance between the cities B and C = 285 km
Distance between the cities A and C = 152 km
By applying cosine rule in triangle ABC,
AB² = AC² + BC² - 2(AC)(BC)CosC
(223)² = (152)² + (285)² - 2(152)(285)CosC
49729 = 23104 + 81225 - (86640)CosC
CosC = [tex]\frac{54600}{86640}[/tex]
CosC = 0.630194
C = [tex]\text{Cos}^{-1}(0.630194)[/tex]
C = 50.94°
Therefore, angle between the lines of sight to cities A and B is 50.94°

The measure of two angles are (2x + 12)o and (5x − 9)o.
What is the value of x if these angles are congruent?
please dont answer if you dont know the answer
Answer:
x=7
Step-by-step explanation:
To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.
get the xs on one side and the whole numbers on the other.
that leaves you with 21=3x.
divide by 3 on both sides to get the answer of x=7
I think the value of x for these two angles is 7
Which rule describes the composition of transformations that maps ABC to A"B"C"?
O T-6.-2°rx-axis(x, y)
O rx-axis° T-6 -2(x, )
O T-6.-2°Ro, 90°(x,y)
O RO, 90° T -6, -2(x, y)
Answer:
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2) ⇒ B
Step-by-step explanation:
Let us revise some rules of transformation
If the point (x, y) reflected across the x-axis, then its image is (x, -y), the rule of reflection is rx-axis (x, y) → (x, -y)If The point (x, y) reflected across the y-axis, then its image is (-x, y), the rule of reflection is ry-axis (x, y) → (-x, y)If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)Look at the graph and list the vertice of each triangle
∵ A = (5, -5) and A' = (5, 5)
∵ B = (1, -2) and B' = (1, 2)
∵ C = (1, -5) and C' = (1, 5)
→ The signs of y-coordinates of all vertices of ΔABC are opposite
in ΔA'B'C'
∴ Δ ABC is reflected across the x-axis
∴ The rule is rx-axis (x, y) → (x, -y)
∵ A' = (5, 5) and A" = (-1, 3)
∵ -1 - 5 = -6 and 3 - 5 = -2
∵ B' = (1, 2) and B" = (-5, 0)
∵ -5 -1 = -6 and 0 - 2 = -2
∵ C' = (1, 5) and C" = (-5,3)
∵ -5 - 1 = -6 and 3 - 5 = -2
→ That means every x-coordinate in Δ A'B'C' added by -6 and every
y-coordinate add by -2
∴ Δ A'B'C' is translated 6 units to the left and 2 units down
∴ The rule is T (x, y) → (x - 6, y - 2)
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2)
Transformation involves changing the position of a shape.
The transformation rule is (b) rx-axis° T-6 -2(x, y
First, triangle ABC is rotated across the x-axis.
The rule of this transformation is represented as: rx
Next, the resulting shape (i.e. triangle A'B'C') is translated 6 units left and 2 units down.
Using the coordinates of A as a guide, we have:
[tex]\mathbf{A = (5,-5)}[/tex]
Apply the first transformation: Rotate across the x-axis
[tex]\mathbf{A' = (5,5)}[/tex]
Apply the second transformation: Translate 6 units left, and 2 units down
[tex]\mathbf{A" = (5 - 6,5-2)}[/tex]
[tex]\mathbf{A" = (- 1,3)}[/tex]
Hence, the transformation rule is (b)

Which of these is defined as a part of a line that is bounded by two end points?
ray
angle
point
line segment
Answer: Line Segment.
Step-by-step explanation:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints. In geometry, a line segment is often denoted using a line above the symbols for the two endpoints (such as ĀB).

-3x-9=27x-6(5x-9) plz help
Answer:
No Solution
Step-by-step explanation:
Use the distributive property, to take out the contents from the parentheses
-6 * 5x = -30x
-6 * -9 = 54
-30x + 54
27x -30x + 54
Combine the terms that have the same variable
27x + -30x = -3x
-3x + 54
-3x - 9 = -3x + 54
Combine terms that have the same variable
-3x + 3x = 0
-9 = 54
-9 does not equal 54, therefore there is no solution

A side of the triangle below has been extended to form an exterior angle of 164º. Find the value of x.
Answer:
x=50
Step-by-step explanation:
The value of the angle of the triangle 'x' will be 111°.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The sum of the two interior angles of the triangle is equal to the exterior angle of the triangle.
x + 53° = 164°
Simplify the equation, then we have
x + 53° = 164°
x = 164° - 53°
x = 111°
The value of the angle of the triangle 'x' will be 111°.

PLEASE HELP!50 POINTS! Brainiest if you know how to do it. I will report you if you're just guessing or very wrong. How do I find the least common denominator in these?
Which of the following is the least common denominator for w-5/w-7 and w+8/3w?
A. 3w (w − 7)
B. w (w − 7)
C. 3w − 7
D. 3(w + 7)
Answer:
A) 3w(w-7)
Step-by-step explanation:
[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]
w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.
Therefore:
3w(w-7) would be your LCD.
Answer:
A. 3w (w − 7)Step-by-step explanation:
GivenFractions
(w- 5)/(w-7) and (w + 8)/3wTo findCommon denominatorSolutionWe observe that the fractions can't be simplified any more and they are in the simplest form
Next, the denominators w - 7 and 3w don't have common factors
Therefore the common denominator is the product of denominators:

a (c-b) = d
[tex]a(c - b) = d[/tex]
Divided sides by a
[tex] \frac{a}{a}(c - b) = \frac{d}{a} \\ [/tex]
[tex]c - b = \frac{d}{a} \\ [/tex]
Plus sides b
[tex]c - b + b = \frac{d}{a} + b \\ [/tex]
[tex]c = \frac{d}{a} + b \\ [/tex]
Done.....♥️♥️♥️♥️♥️
Answer:
[tex]c = \frac{ab + d}{a}[/tex]
Step-by-step explanation:
Step 1: Add ab to both sides.
−ab + ac + ab = d + ab
ac = ab + d
Step 2: Divide both sides by a.
[tex]\frac{ac}{a} =\frac{ab + d}{a}[/tex]
[tex]c = \frac{ab + d}{a}[/tex]
