Answer:
Law of Sines
Step-by-step explanation:
Law of Sines: 
Step 1: Solve for m∠B

25sinx = 27sin36°
sinx = 27sin36°/25

m∠B ≈ 39.4°
Step 3: Find m∠C
180 - (36 + 39.4)
180 - 75.4
m∠C = 104.6°
Step-by-step explanation:
coefficient of x is 17
coefficient of y is -5
coefficient of constant term: 3 + 19 + 10 = 32
