This trapezoid represents the base of a right prism that has a surface area of 2112 square feet.

What is the height of the prism?

Enter your answer in the box.

ft

Answers

The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter (h=3/p ft).

The surface area of the right prism is 2112 sq feet.

The length of two parallel sides of the trapezoid is 31 feet and 13 feet and the height is 16 feet.

What is the surface area of the right prism?

If the side edges of a prism are perpendicular to its ends or the base, it is called a right prism.

The surface area of the right prism is 2×base area+ perimeter×height

area of base or trapezoid = [tex]\rm \frac{1}{2} \times (sum \: of \: parallel \: sides) \times h[/tex]

[tex]\rm \frac{1}{2} \times (13+31) \times 16\\=352\: ft^{2}[/tex]

The surface area of the right prism = 2B ×Ph

[tex]\rm 2112 = 2\times 352+Ph\\\rm 2112 \div 704 = Ph\\[/tex]

h= 3/p ft

The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter.

Answer:

[tex]143.8\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]

Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]

Thus, the total area of the figure is:

[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]

Triangle Review 2.0 (Math i need help please)

Answers

Answer:

A= 30

Step-by-step explanation:

This requires several steps.

First, you need to find the 2 other missing angles.

One can be found easily by substracting 130 from 180

so 180-130 = 50

The other angle is the same as 8x+4

Now set up your equation

180=3x-6 + 8x+4 +50

180 = 3x + 8x -6 + 4 +50

180+6-4-50 = 11x

132 = 11x

132/11 = x

12 = x

Now plug in 12 for x in your angle A

A=3x-6

A=3 * 12 - 6

A=36 - 6

A= 30
