Can somebody help me solve a problem using law of sines?

Due to wind, a tree grew so that it leaned 8 degrees from the vertical. From a point on the ground 28 meters from the base of the tree, the angle of elevation to the top of the the tree is 24.6 degrees. What is the height of the tree?

The answer I got is 21.63 degrees. Is it correct?

It's asking for the height, so you should have an answer in meters.

Answer:
12.163 m
