From the top of the Metro Building, the angle of elevation of the top of the Gammapro Building is 24° and the angle of depression to the foot of the Gammapro Building is 56°. If the buildings are 45 m apart, determine the height of each building to the nearest meter.

Answer 1

Metro: 45tan56°
Gammapro: 45(tan56°+tan24°)

It always helps in these problems to draw a diagram. Then you can see which sides of the triangle you have, and so which trig functions to use.

Of course, it also helps to review your trig functions, and study the similar examples in your text...

Answer 2

56

Answer 3

Metro: 15.58m
Gammapro: 31.16m
