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

`\cos(35.3) = 0.8141 \\ \cos(35.3) = (42.5)/(x) \\ 0.8141 = (42.5)/(x ) \\ x = (42.5)/(0.8141) = 52.20 \: ft`
