Solve for x.

A.40
B.55
C.20
D.35

20

Step-by-step explanation:

The angles are vertical angles which means they are equal

60 = 2x+20

Subtract 20 from each side

60-20 = 2x+20-20

40 =2x

Divide by 2

40/2 = 2x/2

20 =x

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
