Homework Help: PRE-CALC HELP

Posted by JOHN on Friday, November 8, 2013 at 7:25pm.

A communications tower is located at the top of a steep hill, as shown. The angle of inclination of the hill is 58. A guy wire is to be attached to the top of the tower and to the ground, 150 m downhill from the base of the tower. The angle α in the figure is determined to be 7. Find the length of cable required for the guy wire. (Round your answer to the nearest meter.)

All I know is that this question has something to do with law of sine and that's all.

Thank you!
