Answer:
1.
1. Same side exterior angles
2. They are supplementary angles
3. VUW = 80
2. x = 40
3. x = 6
4. x = 8
Explanation:
1.
1.
Same side exterior angles
2.
They are supplementary angles
3.
100 + 100 = 200
360 - 200 = 160
160 / 2 = 80
2.
110 = 3x - 10
110 + 10 = 3x
120 = 3x
120 / 3 = x
x = 40
3.
115 + 115 = 230
360 - 230 = 130
130 / 2 = 65
65 = 8x + 17
65 - 17 = 8x
48 = 8x
48 / 8 = x
x = 6
4.
102 + 102 = 204
360 - 204 = 156
156 / 2 = 78
78 = 10x - 2
78 + 2 = 10x
80 = 10x
80 / 10 = x
x = 8
