Answer:

70º

Step-by-step explanation:

A straight line is 180º You should know that a right angle is 90º

90+20=110

Next you need to subtract 110 from 180

And you get 70

I hope that this is the right answer!

Answer:

70 degrees

Step-by-step explanation:

Straight angles always equal 180 degrees

One angle is 20 degrees and the angle with the box is 90 degrees

90+20=110

180-110=70
