The car travelled 87ft.
Step-by-step explanation:
A) Let the distance between his initial position and the building be 'a'
Height of the building = 150ft
Angle of depression= 42°
tan 42° = a/150
0.90 = a/150
0.90 x 150 = a
a = 135ft.
B) Let the distance between the building and the final position of Tony be 'b'
Height of the building = 150ft.
Angle of depression = 18°
tan 18° = b/150
0.32 = b/150
0.32 x 150 = b
b = 48ft
The distance the car travelled = a - b
= 135 - 48
= 87 ft.
The car travelled 87ft.
