Question

For number 5, which equation do I have to use?

Answer 1

Answer:

x=6

Step-by-step explanation:

The two angles given are corresponding angles.  Corresponding angles on parallel lines are equal.

22x-2 = 21x+4

Subtract 21x from each side

22x-21x-2 =21x-21x+4

x -2 = 4

Add 2 to each side

x-2+2 = 4+2

x = 6

To find the measure of each angle

21x+4

21(6) +4

126+4
