Question

two observers P and Q, 75 metres apart observes a kite (k) in the same vertical plane from the same side of the kite. The angle of elevation of the kote from P and Q are 35° and 95° respectively find the height of the kite to the nearest metre?

Answer 1

The angle of elevation cannot be greater than 90°.
I guess you could think of such an angle, but in that case the observer would be looking back over his shoulder.

Suppose you fix the typo, and then note that if the two angles are x and y, with x < y, and the height of the kit is h, then draw a diagram and you can see that

h cotx - h coty = 75
so,
h = 75/(cotx-coty)
