Solve the Problem $52.83 \mathrm { mph }$ B) $81.35 \mathrm { mph }$

Solve the problem.
-Any offset between a stationary radar gun and a moving target creates a ʺcosine effectʺ that reduces the radar mileage reading by the cosine of the angle between the gun and the vehicle. That
Is, the radar speed reading is the product of the actual reading and the cosine of the angle. Find the
Radar reading to the nearest hundredth for the auto shown in the figure.

A) $52.83 \mathrm { mph }$
B) $81.35 \mathrm { mph }$
C) $96.16 \mathrm { mph }$
D) $97.84 \mathrm { mph }$
