Draw a picture of the triangle formed by Wendy, the car, and the base of the building. The side of the triangle opposite of the 75° angle is 145 feet. The side of the triangle adjacent to the angle is x. Use tangent:
tan 75 = 145 / x
x = 145 / tan 75
x = 38.85
The car is 38.85 feet from the base of the building.
