Question

Help i forgot how to do this and this is one of the last questions on my summer homework

Answer 1

162 degrees

Explanation:

These two angles add up to 180.

8x + 10 + 2x - 20 =180 Next combine the x terms and the constant terms

10x -10 = 180 Next Add 10 to both sides

10x = 190 D Next divide both sides by 10

x = 19. Now that we know x, we can solve for <AXB

8x + 10

8(19) + 10

152 + 10 = 162

Answer 2

162°

Explanation:

They are on a straight line so add to 180

8x + 10 + 2x - 20 = 180

10x - 10 = 180

10x = 190

x = 19

We want AXB so 8x + 10 where x = 19

8(19) + 10 = 162 so it is 162°
