s = 36 degrees

Step-by-step explanation:

We have 180 degrees, which is the half circle.  We also have the 58 degrees, (s-4) degrees, and there is a right angle, so we also have 90 degrees.

Our equation:

180 = 90 + 58 + (s-4)  Add 90 and 58

180 = 148 + (s-4)  Subtract 148 from both sides

-148   -148

32 = s - 4   Add 4 to both sides

+4       +4

36 = s
