Answer:

21

Explanation:

First set up the equation

130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)

then start to solve to find x

130 +2x + 30 + 22 = 180

182 + 2x = 180

-182 -182

2x = -2

/2 /2

x = -1

Then just plug it back into the equation

-1 + 22

21

Answer:

This is the exterior angle theorem, so

x+30+x+22=130

2x+52=130

2x=78

x=39

sooooooooooooo

39+22=61 degrees

61 degrees
