Answer 1

242.4 ft

Explanation:

The angle immediately adjacent to the 29° angle is (90° - 29°) , or 61°.

The cosine function relates this 61° angle to the 500 ft hypotenuse and the unknown adjacent side y:

y

cos 61° = -----------

500 ft

so that y = (500 ft)(cos 61°) = (500 ft)(cos 61°) = (500 ft)(0.485) = 242.4 ft
