Answer:
Explanation:
1. b. Alt. Exterior angles
a. 7x + 8 = 6x + 18
c. x + 8 = 18
x = 10
d. 6(10) + 18 = 60 + 18 = 78
7(10) + 8 = 70 + 8 = 78
2. 15x + 10 + 12x + 8 = 180
same side angles
27x + 18 = 180
27x = 162
x = 6
15(6) + 10 = 90 + 10 = 100 degrees
12(6) + 8 = 72 + 8 = 80 degrees
3. 12x + 2 = 11x + 6
x + 2 = 6
x = 4
12(4) + 2 = 48 + 2 = 50 degrees
11(4) + 6 = 44 + 6 = 50 degrees
corresponding angles
