An acute triangle has two sides measuring 8 cm and 10 cm. What is the best representation of the possible range of
alues for the third side, s?
2< s < 18
!!!!!!! 6
Os<2 ors > 18
s< 6 or s> 12.8
Answer:
1st option
Step-by-step explanation:
given 2 sides of a triangle then the third side s is in the range
difference of 2 sides < s < sum of 2 sides , that is
10 - 8 < s < 10 + 8
2 < s < 18

Answer:
x=45, y=45, z= 131
Step-by-step explanation:
x and y makes up a right angle (90). You can even;y split them in half, which is 45 degrees. Therefore, x= 45 and y also = 45.
Now that there are 2 right angles, that makes up 180. 180+49=229
A full rotation is 360, so you subtract that. 360-229=131
z=131.
Answer:
x = 41°y = 49°z = 131°Step-by-step explanation:
The relevant relations are ...
a straight angle measures 180°a right angle measures 90°vertical angles have the same measure__
The angle marked 49° and the one marked "y" are vertical angles, so have the same measure.
y = 49°
The angle marked "x" and the angle marked "y" together make up a right angle, so total 90°.
x + y = 90°
x + 49° = 90°
x = 41° . . . . . . . . . subtract 49°
The angle marked z and the one marked 49° together make up a straight angle, so total 180°. (They are a "linear pair.")
49° +z = 180°
z = 131° . . . . . . . subtract 49°
The measures of the marked angles are ...
x = 41°
y = 49°
z = 131°

What is the surface area for a rectangular prism with the height of 6 inches, width of 8 inches, and the length of 4 inches
Answer:
Using the formula, we can find that the surface area is 208 in².
Step-by-step explanation:
To find the surface area (SA) for a rectangular prism, substitute its dimensions into the formula and solve.
DimensionsDimensions mean the side lengths of the shape, the height, width and length. We know the dimensions from the question.
Height: h = 6 in
Width: w = 8 in
Length: l = 4 in
FormulaWe will need the formula to find the surface area for rectangular prisms. Note that different shapes have a different formula for finding surface area.
[tex]SA= 2(lw + lh + hw)[/tex]
Substitute the dimensions h = 6in, w = 8in and l = 4in into the formula.
[tex]SA= 2((4\ in)(8\ in) + (4\ in)(6\ in) + (6\ in)(8\ in))[/tex]
Remember order of operations (BEDMAS) when solving. Multiply within the brackets first.
[tex]SA= 2(32\ in^{2} + 24\ in^{2} + 48\ in^{2})[/tex] Add within the brackets.
[tex]SA= 2(104\ in^{2})[/tex] Multiply.
[tex]SA= 208\ in^{2}[/tex] Final answer
Tip: The final answer for area will always have squared units.
∴ The surface area (SA) of the rectangular prism with a height of 6 inches, width of 8 inches, and length of 4 inches is 208 squared inches.

speed = distance/time
4 P = 1 House / 10 Days
P = 1 House / 40 Days
Let T = Time it takes for five painters.
5 P = 1 House / T
5(1/40) = 1 /T

Find the surface area and lateral area of the following three prisms. Be sure to show all of your work.
Problem 1
L = 10 = length
W = 5 = width
H = 4 = height
SA = surface area of a rectangular prism, aka block or box
SA = 2*(LW+LH+WH)
SA = 2*(10*5+10*4+5*4)
SA = 220
--------------------
LA = lateral area, aka wall area
LA = (perimeter of the base)*(height)
LA = (2L+2W)*H
LA = (2*10+2*5)*4
LA = 120
or
LA = SA - (floor area) - (ceiling area)
LA = SA - 2*(area of the floor)
LA = 220 - 2*(LW)
LA = 220 - 2*(10*5)
LA = 220 - 100
LA = 120
--------------------
Answers:
Surface Area = 220 square feet
Lateral Area = 120 square feet
==========================================================
Problem 2
Imagine rotating the object so that the triangular face is resting on the flat ground. This means the triangular faces are the floor and ceiling. The walls of any prism are always rectangles.
Focus on the right triangle with leg b = 4 and hypotenuse c = 5.
Use the pythagorean theorem to find that a = 3 is the missing leg length.
The triangle has base = 4 and height = 3, so its area is base*height/2 = 4*3/2 = 6 square inches. This is the area of the floor and ceiling each.
--------------------
This is the summary so far
base or floor area = 6 square inchesdepth of the prism = 8 inches(a,b,c) = (3,4,5) are the sides of the right triangleThose values are then plugged into the formulas below.
SA = surface area of a triangular prism
SA = 2*(base area) + depth*(a+b+c)
SA = 2*(6) + 8*(3+4+5)
SA = 108
LA = lateral area
LA = depth*(a+b+c)
LA = 8*(3+4+5)
LA = 96
or
LA = SA - 2*(floor area)
LA = 108 - 2*(6)
LA = 96
Note that a+b+c = perimeter of the triangular base.

Problem 3
Imagine rotating the figure so that the octagon is resting on the flat ground.
Refer to the screenshot below to see the steps on computing the area of the regular octagon, aka the floor area.
The floor area is approximately 120.710678 square cm. The same goes with the ceiling because the floor and ceiling are congruent regular octagons that are parallel.
Each rectangular wall has an area of 5*22 = 110 square cm. Eight identical walls give a total lateral area of 8*110 = 880 square cm.
Add the floor and ceiling area to the wall area to get the total surface area
floor + ceiling + walls = 120.710678 + 120.710678 + 880 = 1121.421356

A wire of length 4x is bent into the shape of a circle. A. Express the circumference of the circle as a function of 4x. B. Express the area of the circle as a function of 4x.
The circumference of the wire is 4x and the area of the circle is 4x^2/π
How to determine the circumference?The length of the wire is given as;
Length = 4x
This represents the circumference.
Hence, the circumference of the wire is 4x
How to determine the area?In (a), we have:
Circumference = 4x
Calculate the radius using:
2πr = 4x
Divide through by 2π
r = 2x/π
The area is:
Area = πr^2
This gives
Area = π(2x/π)^2
Evaluate
Area = 4x^2/π
Hence, the area of the circle is 4x^2/π
