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,
