Answer:
y = 42°
Step-by-step explanation:
The third vertex in the triangle with y is adjacent to a right angle, thus is right.
The sum of the 3 angles in a triangle = 180°, then
y = 180° - (90 + 48)° = 180° - 138° = 42°
Y= 42

ABC and ACD are triangles
a) Show that AC=11.4cm, correct to 3 significant figures.
Answers
Answer: 17² + 13² - 2 × 17 × 13 × COS(42) = 11.38112416
AC = 11.38112416 correct to 3 significant figures = 11.4cm
Thanks for helping me on part B :)
Step-by-step explanation:
The length of AC is 11.4 centimeters and the length of BC is 30.9 centimeters.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
ΔABC and ΔACD are two triangles.
A. The value of AC will be
Using the cosine rule,
AC² = AD² + AC² - 2 × AD × AC × cos D
AC² = 17² + 13² - 2 × 17 × 13 × cos 42
AC² = 289 + 169 - 328.47
AC² = 129.52
AC = 11.4 cm
B. The value of BC will be
Using the sine rule,
[tex]\rm \dfrac{BC}{sin A} = \dfrac{CA}{sin B} = \dfrac{AB}{sin C}\\\\\dfrac{BC}{sin 76} = \dfrac{11.4}{sin 21 } =\dfrac{AB}{sin 83 }[/tex]
From the first 2, we have
[tex]\rm \dfrac{BC}{sin 76} = \dfrac{11.4}{sin 21 } \\\\B \ C \ \ = 30.9[/tex]
Thus, the length of AC is 11.4 centimeters and the length of BC is 30.9 centimeters.

Answer:
(3, -1)
Step-by-step explanation:
3x +y = 8
-3x =-3x
Y=-3x +8 Substitute into 1st equation y=-3x+8
2x-7(8-3x+8)= 13 -3(3) + 8
2x-56+21x= 13 -9 +8
23x-56 =13 y = -1

If p is inversely proportional to the square of q, and p is 30 when q is 10 determine p when q is equal to 5
Answers
Answer:
The value of p = 120 when q = 5
Step-by-step explanation:
We know that if y varies inversely with x, we get the equation
y ∝ 1/x
y = k/x
k = yx
where 'k' is called the constant of proportionality.
In our case,
If p is inversely proportional to the square of q, then
p ∝ 1/q²
p = k/q²
k = pq²
As p is 30 when q is 10, so
substituting p = 30 and q = 10
k = (30) (10)²
k = (30)(100)
k = 3000
Now,
Determining the value of p when q = 5
Using the equation
p = k/q²
now substituting k = 3000 and q = 5
p = 3000 / (5)²
p = 3000/25
p = 120
Therefore, the value of p = 120 when q = 5

Answers
Answer:
It doesn't
Step-by-step explanation:
When a shape is scaled up or down, the angles don't change.

What is the area of the regular hexagon ABCDEF? Explain your reasoning.
Answers
Answer:
2340 units²
Step-by-step explanation:
The easiest way to solve for the area of the hexagon is to find the area of the rectangle and subtracting the area of the triangles from it.
First, find the area of the rectangle:
A(rectangle) = (15 + 30 + 15)(26 + 26)
A(rectangle) = (60)(52)
A(rectangle) = 3120
Next, find the area of the 4 triangles:
A(triangles) = 1/2(15)(26) · 4
A(triangles) = 195 · 4
A(triangles) = 780
Finally, subtract the two areas to find the area of the hexagon:
A(hexagon) = 3120 - 780
A(hexagon) = 2340
Based on the information given the area of hexagon is 2340.
Area of hexagon:First step is to find the area of the rectangle:
Area of rectangle= (15 + 30 + 15)(26 + 26)
Area of rectangle=60×52
Area of rectangle= 3120
Second step is to find the area of the 4 triangles:
Area of rectangle =[1/2(15)(26)]×4
Area of rectangle= 195 × 4
Area of rectangle= 780
Third step is to find the area of hexagon:
Area of hexagon= 3120 - 780
Area of hexagon=2340
Inconclusion the area of hexagon is 2340.
