Question

A moving sidewalk takes zoo visitors up a hill. The

sidewalk rises 48 feet. Its angle of elevation is 15º.
About how long is the sidewalk?

Answer 1

x = 185.458 ft

Explanation:

When we draw a picture, we are able to see that we need to use sin∅ to solve this problem:

sin15° = 48/x

xsin15° = 48

x = 48/sin14°
