Answer 1

3

Explanation:

Both angles are congruent because they are opposite exterior angles.

6x+2=x+17

5x=15

x=3

Answer 2

x = 23 °

Explanation:

6 x + 2 ° + x + 17 ° = 180 °

combine like terms

6x + x + 2 ° + 17 ° = 180 °

7 x + 19 ° = 180 °

7 x = 180 ° - 19 °

7 x = 161 °

x = 161 ° / 7

x = 23 °
