Both angles are 30 degrees. Hope this helps

Answer:

x=20

Step-by-step explanation:

Complementary means =90 degrees, so with that being said, you need to write the equation as follows:

2x+10+x+20=90

Then add like terms:

3x+30=90

Subtract 30 from both sides (30 and 90)

3x=60

Divide both sides by 3

x=20

I hope this helps!!
