Write each of the numbers 1, 4, 9, 16 and 25 as a based raised to the second power. explain why these numbers sometimes are called ''perfect squares".

been looking for the answer havent been able to find it   but good luck with it

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.
