Question 1181296: A person looks up at the building 100m tall. The angle of elevation is 𝟐𝟐°. Find:
a. The distance from the person to the base of the building
b. The person needs to change an angle of elevation to make it 𝟒𝟎°. By how much
closer should the person move closer to the building? Answer by mananth(16946) (Show Source):
tan 22 = BG/GM
GM = BG/tan 22 = 247.50
tan 40 = 100/(247.50-x)
100/tan 40 = 247.50 -x
119 =247.50-x
x= 247.50-119
x= 128.3
He has to move 128.30m towards the building
.
