Find values of x that makes m ll n

x=8

Step-by-step explanation:

(15x+10)+(6x+2)=180            

one line is 180 degrees. let's focus our attention on the line M. it goes up and down with two different angles and those two angles should add up to 180 degrees to form a straight line. if you now look at like n, you will see the missing angle from line m is in the angle of line n. so you need to add the two equations together to equal 180.

21x+12=180

we used the distributive property by adding 15x and 6x together as well as 10 and 2 together.

21x=168

we subtracted 12 from both sides

x=8

we divided each side by 21 to isolate x.
