Which additional fact proves that δrst and δwxy are congruent if ∠t ≅ ∠y and rt ≅ wy? assume the following: ∠w = x + 5 ∠x = 3x - 9 ∠y = 2x + 4 a) ∠s = 2x + 20 b) ∠r = 2x + 20 c) ∠s = 2x 2 + 5 d) ∠r = 2x 2 + 5

The correct answer is answer choice D.

Step-by-step explanation:

∠R =

2x

2

+ 5

x + 5 + 3x - 9 + 2x + 4 = 180

x = 30

then,

∠W = x + 5 = 30 + 5 = 35

∠R =

2x

2

+ 5 =

2(30)

2

+ 5 =

60

2

+ 5 = 35

thus, ∠W ≅ ∠R
