Question

I eliminated the last answer so it’s one of the other ones pls help

Answer 1

x=72

Explanation:

This is a straight line so

x+y = 180

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

Angle x =2n+12

= 2(30)+12

= 60 +12

=72
