When the top (T) of a mountain is viewed from point A, 2000m from ground, the angle of depression (a) is equal to 15° and when it is viewed from point B on the ground, the angle of elevation (b) is equal to 10°. If points A and B are on the same vertical line, find the height (h) of the mountain. A a = 15° T 2000 m B b = 10°
