State the type of angles and solve for the yven vatizble. 3x
€
(2x + 20)
Aterate bretor Andes, x-20
Alternate Interior Anges, x = 20
Corresponding Anges, x=4
Same Side Interior Anges, 4

1st option

Step-by-step explanation:

The 2 angles are alternate exterior angles and are congruent , so

3x = 2x + 20 ( subtract 2x from both sides )

x = 20

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
