The measure of the supplement of a 129 degree angle

The supplement is 51 degrees

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let x be the supplement

x+129 = 180

Subtract 129 from each side

x+129-129 = 180-129

x =51

u what ?

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.
