Answer 1

X= 140 degrees.

Explanation:

First, we see that 20 +x + (40-20).

Then we keep in mind that 40-20=20

so 180-40+x=

140 degrees!

Answer 2

half a circle is 180 degrees and we have to find x what we know is that one angle is 20 therefore the other side must be equal to 20 as well. Now that we know that we can add 20 +20 and we get 40. Now we can minus 40 from 180 therefore X is equal to 140.
