6] c. 120°
< AED = 180° - < CED
< AED = 180° - 60°
< AED = 120°
7] c. 65°
< CFE = 180° - 115°
< CFE = 65°
8] b. 40°
< PQS + < RQS = 180°
3x + 20° + 40° = 180°
3x + 60° = 180°
3x = 180° - 60°
3x = 120°
x = 120°/3
x = 40°
9] d. 56°
< RQT + < SQT = 90°
3b + 5° + 2b = 90°
5b + 5° = 90°
5b = 90° - 5°
5b = 85°
b = 85°/5
b = 17°
< RQT = 3b + 5°
< RQT = 3(17°) + 5°
< RQT = 51° + 5°
< RQT = 56°
10] b. 20
5a + 50° + 30° = 180°
5a + 80° = 180°
5a = 180° - 80°
5a = 100°
a = 100°/5
a = 20°
