If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will not have defects?

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
