Question

11. A surveyor is 100 meters from a bridge. The angle of elevation to the top of the bridge is 35º. The

surveyor's instrument is 1.45 meters above the ground. Find the height of the bridge.

Answer 1

The height of the bridge is 71.47 m.

Explanation:

Since the eye of the surveyor is 1.45m creating the horizontal distance, we must add the 1.45 m to the 70.02 m to determine the total height of the bridge.

70.02 m + 1.45 m = 71.47 m

The height of the bridge is 71.47 m.
