Mt. Rushmore is approximately 6000 feet tall. As you go up in altitude, the temperature decreases at a rate of about 5°F for every 1000 feet. If the temperature at the top of Mt. Rushmore is 4°F, what is the temperature at a camp located at 2000 feet above sea level?

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.

answer: 88
