Answer: A) 50

=================================================

Step-by-step explanation:

Angles 1 and 3 are vertical angles which are congruent.

angle 1 = angle 3

110 = 2x+10

2x+10 = 110

2x = 110-10

2x = 100

x = 100/2

x = 50

x=50

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.
