A 30foot flagstaff is fixed in the center of a circular tower 40 feet in diameter. From a point in the same horizontal plane as the foot of the tower the angles of elevation of the top of the flagstaff and the top of the tower are found to be 36 and 30 degree respectively. Find the height of the tower.

    The poster had forgotten to give one of the angles and in Steve's solution he called it A.

    In your problem we know A = 36°
    so all you have to do is replace A with 36 and go for it.

    You should get appr 59.86
