Question

Which additional fact proves that ΔRST and ΔWXY are congruent if ∠T ≅ ∠Y and RT ≅ WY.

∠W = x + 2
∠X = x - 6
∠Y = 2x + 4

Answer 1

"B" I just did it this will help you :-)

Answer 2

∠S = 2x/3 + 9

x+2+x+2x+4=180
x=45

Then,


`∠`X=x-6=45-6=39
∠S=2x/3 + 9 = 2(45)/3 +9=30+9=39
~
thus, ∠X = ∠S
