Tan 15 = h/d
Tan 15 = 145/d
d = 145/Tan 15 = 541.2 Ft.
Or if the angle between the line of
sight and the ver.(145Ft) is 15o, then
Tan 15 = d/145
d = 145*Tan 15 = 38.85 Ft.
Wendy spots a pizza delivery car as she is looking down at a 15° angle from the top of her apartment building, which is 145 ft tall. How far away is the car from the base of the building? Round to the nearest hundredth.
A. 45.98 ft
B. 3.56 ft
C. 38.85 ft
D. 68.78 ft
I keep following the tan^-1(h/d) formula for this but it won't give me any of the multiple choice answers. I've even done it through a calculator (15 = tan^-1[145/x]). I also did 15/tan(145) and 15/tan^-1(145).
