Answer 2

x = 72

Explanation:

x+y = 180 since they make a straight line

x = 2n+12 and y = 3n+18

2n+12 + 3n+18 = 180

Combine like terms

5n+30 = 180

Subtract 30 from each side

5n+30-30 = 180-30

5n = 150

Divide by 5

5n/5 = 150/5

n = 30

We want to find angle x

x = 2n+12

= 2(30)+12

= 60+12

=72
