Answer:
2π radians
Step-by-step explanation:
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees
First step is replacing x with -4. => -3=5y+8 => 5y= -8-3 => y =-11/5
