Answer:
x=3
Explanation:
since 67 and 23x-2 are congruent angles, you can set them equal to each other and solve ~OR~ since 5x+98 and 23x-2 are supplementary angles you can add them and have that equal to 180.
First Option:
67 = 23x-2
-2 -2
65=23x
/23 /23
3=x
Second Option:
5x+98 + 23x-2 = 180
combine like terms
28x+96=180
-96 -96
28x=84
/28 /28
First thing first we will use the alternate exterior angles theorem,
Since 67 and 23x-2 are alternate exterior angles, they are equal
