Any offset between a stationary radar gun and a moving target creates a "cosine effect" 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 readings to the nearest hundreth for Auto A and Auto B Don't have picture but Auto A is 10 dgree angle and actual speed of 70mph and B is 20 degrees with 70mph. Do I find the cosine of the angle given to me and then multiply it by 70?

Vocaloid:
yeah that's right
Vocaloid:
so for A it would be 70 * cos(10) and similarly for B

Oh okay! Just making sure of how to do it. Really hate word problems.
