If a = 57 m, b = 65 m, and angle C = 86 degrees, then what is the area of triangle ABC to the nearest square m

Question

If a = 57 m, b = 65 m, and angle C = 86 degrees, then what is the area of triangle ABC to the nearest square meter? _ m^2.

GPT-5 mini · Answer

Area = (1/2)ab sin C = 0.5(57)(65) sin 86° = 1852.5 × sin 86° ≈ 1852.5 × 0.997564 ≈ 1847.99 ≈ 1848 m^2.

Answer: 1848 m^2.
