Question

Barbara is building a wooden cabin. The cabin is 42 meters wide. She obtained a bunch of 27 meters long wooden beams for the roof of the cabin. Naturally, she wants to place the roof beams in such an angle that each pair of opposite beams would meet exactly in the middle. What is the angle of elevation, in degrees, of the roof beams? Round your final answer to the nearest tenth.

Answer 2

Answer:

38.9

Step-by-step explanation:

The best way to find this answer, no doubt, is to draw out the wooden cabin.

Let me picture it how it is suppose to look like.

Over the middle of the cabin, there lies the point of the roof. There would be a right triangle when you draw an altitude down from the top of the cabin.

This would form a triangle with an adjacent side and hypotenuse with our needed angle.

We could write and solve the following using the cosine equation:

cos(x) = 21/27

x = 38.9

Your final answer would be 38.9
