The missing angles are:
36) B = 28°
37) G = 48°
How to find the missing angle?
The exterior angle theorem asserts that if a triangle's side gets extended, then the resultant exterior angle will be equal to the total of the two opposite interior angles of the triangle.
36) Using the exterior angle theorem gives:
B + 82 = 110
B = 110 - 82
B = 28°
37) Using the exterior angle theorem gives:
G + 68 = 116
G = 116 - 68
G = 48°
