Question

A power line extends from a light pole 43 meters to the ground and makes an angle of 30 degrees with the ground. To the nearest tenth of a meter, how tall is the light pole?

Answer 1

Hello,

To solve this problem, you should first draw a picture. Then, you can determine which trig ratio that you will use. In this case, you are dealing with the opposite side from the angle and the hypotenuse.

Therefore, you can use the sin ratio. 

Our equation will be:
sin30 = x/43
0.5 = x/43
21.5 = x

The light pole is 21.5 meters tall.

Good luck,
