How do you this?

A. 100
B. 61
C. 85
D. 65

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!
