Solve the triangle. B = 36°, a = 38, c = 18

b ≈ 41.7, C ≈ 28.2, A ≈ 115.8
b ≈ 25.7, C ≈ 24.2, A ≈ 119.8
b ≈ 25.7, C ≈ 116.8, A ≈ 27.2
b ≈ 41.7, C ≈ 24.2, A ≈ 119.8

b ≈ 25.7, C ≈ 24.2, A ≈ 119.8

Step-by-step explanation:

b² = a² + c² - 2ac·cos(B)

b² = 38² + 18² -2·38·18·cos(36°) ≈ 661.26475

b ≈ 25.715

sin(C)/c = sin(B)/b

C = arcsin(c/b·sin(B)) ≈ 24.29515°

∠A can be found as 180° - ∠B - ∠C

A = arcsin(a/b·sin(B)) ≈ 119.70485°

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

283 square feet
