Answer:
61
Step-by-step explanation:
82+37=119. 180-119=61. remember triangles always add up to 180°
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
