Answer:
1. a = 55°
2. b = c = 70°
3. d = 68°
4. e = 107°, f = 73°
5. g = 65°, h = 90°
Step-by-step explanation:
1. they are vertical angles. vertical angles are equal in measurement
2. 110 and b are supplementary, meaning have a sum of 180.
b = 180-110 = 70
b and c are vertical angles. vertical angles are equal in measurement
3. 112 and d are supplementary, meaning have a sum of 180.
d = 180-112 = 68
4. 73 and e are supplementary, meaning have a sum of 180.
e = 180-73 = 107
73 and f are vertical angles. vertical angles are equal in measurement
5. g and 25 are complementary, meaning have a sum of 90.
g = 90-25 = 65
90 and h are supplementary, meaning have a sum of 180.
e = 180-90 = 90
