Question

if a =57 b=5 m and <C = 86 degrees then what is the area of ABC to the nearest square meter

GPT-5 mini · Answer

Use the formula A = (1/2)ab sin C (a and b meet at angle C).

A = 1/2 · 57 · 5 · sin 86°
  = 142.5 · sin 86°
  ≈ 142.5 · 0.997564
  ≈ 142.15 m²

Rounded to the nearest square metre: 142 m².
