Question

Given m is parallel to n, find the value of x.

Answer 1

Since the angles would add up to 180 degrees add up the two pieces of info that you have.
9x+9=180
9x= 171
X=19

Answer 2

Answer:

19

Step-by-step explanation:

The sum of the given angles = 180° because m||n

7x + 7 + 2x + 2 = 180° add like terms

9x + 9 = 180

9x = 171 divide both sides by 9

x = 19
