Question

Find the value of x. round to the nearest tenth.

Answer 1

Explanation:

21.7

Use the cosine function, which is the ratio (adjacent side) / (hypotenuse).

Here we have cos 37 degrees = adj / hyp = 17.3 / x, and so

x 1

------ = -------------------

17.3 cos 37 deg

Then the hypotenuse length, x, is 17.3 / 0.799 = 21.7
