Question

Someone help me with this problem please

Answer 1

Answer is x = (0) zero

Angles around a point will always add up to 360 degrees, so the three angles will add up to 360x

x + 138
x + 50
172

So if we use 0 for x, we have

138 + 50 + 172 which equals 360

So m ∠ QST: 0 + 138 = 138
So m ∠ RSQ: 0 + 50 = 50
And m ∠ RST = 172

Problem solved!
