Answer:

D) 380cm^2

Step-by-step explanation:

In order to find the surface area, find the area of each side then add them all.

The formula for this would be:

base area + 4(side area)

To find the area of the base multiply 10 by 10

10 x 10 = 100

To find the area off the triangle sides multiply the width (10) by the height (14) and divide by 2

(14 x 10) ÷ 2 = 70

Because there are four sides, multiply 70 by 4 then add the product to 100

70 x 4 + 100 = 380cm^2

The US uses roughly 4.0 million Gigawatt-hours per year in electricity. Currently 50% of out electricity comes from coal. If eve

4 trillion pounds.

1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.

Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.

2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.

Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.

What is m∠Q? Round only your final answer to the nearest tenth. 24.1º 30.8º 59.2º 125.1º
Shtirlitz [24]

The measure of the angle m∠Q is 30.8 degree after applying the law of cosine.

<h3>What is the triangle?</h3>

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

Let's suppose the angle m∠Q is A

So applying law of cosine:

\rm 40^2 = 64^2+32^2-2(64)(32) \ cosA

CosA = 0.859

A = 30.75 ≈ 30.8 degree

Thus, the measure of the angle m∠Q is 30.8 degree after applying the law of cosine.
