Answer:
28, 50, and 102 degrees
Step-by-step explanation:
Since the sum of all angles of a triangle = 180 (Angle Sum Property),
(2x-10) + (x+31) + (5x+7) = 180, implies 8x + 28 = 180
Therefore, 8x = 180 - 28 = 152, implies x = 152/8 = 19.
Thus, the angles are : (2x-10) = 28, (x+31) = 50, and (5x+7) = 102.
Hope this helps you!
