Question 1157651: Kayson is looking at two buildings, building A and building B, at an angle of elevation of 59°. Building A is 40 feet away, and building B is 60 feet away. Which building is taller and by approximately how many feet?
Building A; it is around 66.57 feet taller than building B
Building A; it is around 33.29 feet taller than building B
Building B; it is around 66.57 feet taller than building A
Building B; it is around 33.29 feet taller than building A

B is taller and further away. Draw this to see. Closer things look bigger, so if the buildings have the same angular elevation from one spot, the taller building is further away. The hypotenuse touches the top of building A and keeps on going at the same angle to building B, further away.
tan A=ht/40
ht A=40 tan 59=66.57 ft
tan B=ht/60
ht B=60 tan 59=99.86 ft.
The last choice, Building B is taller by 33.29 ft
