3 is your answer

Step-by-step explanation:

What you do is PEMDAS

7 + 3 + (-7) You will add 7 and 3 together first.

10 + (-7) You will subtract 10 and -7

3 is your answer.

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.
