In ΔABC, BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°. What are m∠A and m∠C to two decimal places? A.
m∠A ≈ 25.24°, m∠C ≈ 117.76°

B.
m∠A ≈ 58.15°, m∠C ≈ 84.85°

C.
m∠A ≈ 25.24°, m∠C ≈ 64.76°

D.
m∠A ≈ 58.15°, m∠C ≈ 31.85°

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
