Question

Someone actually please help me thank you

Answer 1

Since a straight line will always be 180,
If you take 69+x=180 it will make this a lot easier
Simply rearrange it to get x=180-69 and you’ll get 111
Hope this helps

Answer 2

b+69=180 because they are angles on a straight line.

To find b you group like terms or subtract 69 from both sides

b+69-69=180-69

b=180-69

b = 111°
