Question

Bob is building a wooden cabin. The cabin is 30 meters wide. He obtained a bunch of 17 meters long wooden beams for the roof of the cabin. Naturally, he 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?

Answer 2

Answer:

28.07°

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Based on the information given to us in the question I have created an illustration better demonstrating the situation. We can see that we have the base length and hypotenuse length. Now we need to find the value of x. We can find the value by using the following formula.

$cos(x) = \frac{adjadent}{hypotenuse}$

$cos(x) = \frac{15}{17}$ .... find the inverse by using arccos

$x = arccos(\frac{15}{17} )$

$x = 28.07$

Finally, we can see that the degree of the angle x is 28.07°
