Question

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

Answer 1

Answer:

162°

Step-by-step 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°

Answer 2

Answer:

162 degrees

Step-by-step 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
