A children's wind-up car toy travels a distance, d inches, as modeled by the function d=12 +8t where t is the number of seconds after the car has been wound up and released. If the car is released at 12 feet, to the nearest second, how many seconds would it take to rcach 21 feet? 0 10

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.

both equations and proportions are better.
