The owner of a roller skating rink plans to buy new equipment in four years. The new equipment has. cost of $85,000. She believes she can earn 10% interest compounded quarterly. Find the amount of each quarterly payment needed. Use the factor 0.05160, which corresponds with 2.5% interest over 16 periods.

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.

won't that be plagrisim thought?
