**helper**, Wednesday, January 26, 2011 at 10:13pmIf I am understanding this picture,

a right triangle is formed with angle A = 50 degrees and side b = 23 (15 + 8).

You need the length of a, which is the streetlamp.

tan A = opp/adj = a/b = a/23

tan 50 = a/23

1.19 = a/23

Solve for a, for your answer
