A wind tower at the top of a hill casts a shadow 30m long along the side of the hill. An observer at the farthest edge of the shadow from the tower estimates the angle of elevation to the top of the tower to be 34degrees. If the slope of the hill is 13degrees from the horizontal, how high is the tower of the nearest metre?

Please show me each step. If you could somehow include a diagram that'd be amazing
Old Teacher it's because I want to make sure.. cause my textbook says the answer is 25 and it was different from yours.

my textbook says 13m and i got 17m
