Answer:
85 degrees
Step-by-step explanation:
So we can see that the two angles form a "c." This c indicates that it is a same side interior angle. Same side interioir angles are equal to 180 degrees. So, set both the expressions to 180.
x+90+x+100=180
2x+190=180
2x=-10
x=-5
Substitute in the value for x
-5+90=85
I hope this helps!
