A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?

Building to the left is taller.

Step-by-step explanation:

Kindly refer to the attached diagram for the given dimensions.

AB and PQ be the two buildings.

The car be parked at point R.

Distance of R from building bases:

BR = 49 m

QR = 56 m

Let us use tangent in

Let us use tangent in

So, building to the left is taller.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
