Question

A fire fighter sees a woman trapped in the building 81 feet up from the bottom floor. If the firetruck is parked 41 feet away from the bottom of the building, at what angle of elevation, to the nearest degree, shut the fire fighter extend the ladder to reach the woman?

Answer 1

Answer:
63 Degrees

Steps:
Use the Pythagorean Theorem to find the missing side.

a^2 + b^2 = c^2
c = SQRT(a^2 + b^2)

c = SQRT(81^2 + 41^2)
c = SQRT(8242)
c = 90.785

ASIN is the inverse of sine.
