151°

Step-by-step explanation:

First, we must identify the geometric figure in the diagram. It has five angles, so it's a pentagon.

It is also important to remember that the sum of all interior angles in a pentagon is 540°. So that means:

5x+2 + 10x-3 + 8x-19 + 13x-31 + 7x-11 = 540

43x-62 = 540

43x = 602

x = 14°

Now, we just plug in value of x into the expression for angle S:

S = 13x-31

S = 13•14-31

S = 151°

c

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel
