Question
A man lies 18 horizontal feet from the base of a wall. He must incline his eyes at an angle of 21 degrees to look at the top of the wall. What is the distance from the man directly to the top of the wall?
Step 1
The horizontal distance from the man to the base of the wall is one leg of the triangle, the height of the wall is the other leg, and the distance from the man to the top of the wall is the hypotenuse. Show more…
