Which expression is equivalent to ? 6.52 – 6. 7(3+6) A. (60)2 · 7(9) B. 6(10)2 - 21 +42 C.6(25)+ 7(9) D. 150 - 21-42​

C

Step-by-step explanation:

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.
