Question

Write down your work. I need it

Answer 1

First, find the angle of ∠RSP. ΔRSP is a triangle. Which means it's interior angles add up to 180 degrees. Find the missing length.

Let x = the missing length

79 + 43 + x = 180
122 + x = 180
x = 58

Now we know the angle of ∠RSP

Angles ∠RSP and ∠RST are supplementary angles. Which means they add up to 180 degrees.

We know the angle of ∠RSP

Find the angle of ∠RST

Let x = the missing angle

x + 58 = 180
x = 122

So, the answer is C 122 degrees.

Answer 2

79+43=122
122+58=180
so the answer is A 58
