Answer:

<em>Similarity doesn't changes angle measures</em>

∠U = 56°, ∠U' = 3x - 16
∠U = ∠U'

a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°

b) ∠T = x + 46 = 24 + 46 = 70°

c) <u>Scale factor:</u>

k = S'T'/ST = 19/57 = 1/3

<u>Find y using known sides and scale factor:</u>

U'V'/UV = 1/3
(y + 4)/63 = 1/3
y + 4 = 21
y = 21 - 4
y = 17
