Step-by-step explanation:
1. Angles are complementary which means they add up to 90°
3x + 6 + 2x - 11 = 90° (angles are complementary)
5x - 5 = 90
5x = 90 + 5
5x = 95
x= 95/5
x= 19
Therefore
m∠G = 3x+6
= 3(19)+6
= 63°
m∠H= 2x-11
= 2(19)-11
= 27°
2. Angles are supplementary which means they add up to 180°
m∠J + 29 = 180°
m∠J= 180-29
m∠J =151°
