Question

The angle of elevation from the top of a building to the top of another is 45°.

The distance between the feet of these two buildings is 402 m.
What is the distance between the top of the two buildings?

Answer 1

402m

Explanation:

Set this up as a triangle and use trig to solve it:

tan(45) = y/402

y = 402*tan(45)

substitute: tan(45) = 1

y = 402 * 1

y = 402m
