A is standing at a point 15 metres away from the base of B’s house which is 15 metres high. What is the angle of elevations of the top?

A. 90°

B. 60°

C. 30°

D. 45°

Let Q be the angle of elevation

therefore, tanQ = BC / AC

= 15 m / 15m

= 1

tanQ = 1

Q = 45

^{0}

Hence option D is the correct answer.
