Question

plz tell faster. if u will tell u will mark u brainliest​

Answer 1

1. linear pairs

x + 145 = 180

x = 180 - 145

x = 35 degree

2. alternate angles

x = 50 degree

3. linear pairs

x + 80 = 180

x = 180 - 80

x = 100 degree

4. linear pairs

x + 62 = 180

x = 180 - 62

x = 118 degree

5. linear pairs

x + 138 = 180

x = 180 - 138

x = 42 degree

6. alternate angles

x = 104 degree

7. linear pairs

x + 68 = 180

x = 180 - 68

x = 112 degree

8. alternate angles

x = 130 degree

9. alternate angles

x = 40 degree
