Question

a guy wire runs from the top of a tree Point 42.5 ft from its base if the angle of elevation from the ground on top of the tree is 35.3 degrees find the length x of The Wire ​

Answer 1

Answer:

$\cos(35.3) = 0.8141 \\ \cos(35.3) = \frac{42.5}{x} \\ 0.8141 = \frac{42.5}{x } \\ x = \frac{42.5}{0.8141} = 52.20 \: ft$
