On an inclined road, which makes an angle of 25 degrees with the horizontal plane, stands a vertical tower. At a point Q, 150 ft from the base of the tower down the road, the angle of elevation to the top of the tower is 65. How high is the tower?

Answer 1

as usual, draw a diagram, and you will see that

(h + 150*sin25°)/(150*cos25°) = tan65°
