Question 158461
You did a great job coming up with your equations.

180 = s + a

s = a - 44

If you notice that the value of s is given in your second equation.

We plug that value into the first equation and solve for a.

180 = a - 44 + a

180 = 2a - 44


180 + 44 = 2a

224 = 2a

224/2 = a

112 = a

This is the angle measure.

=========================

To find it's supplement, plug 112 into your first equation and solve for s.

180 = s + a

180 = s + 112

180 - 112 = s

68 = s
