Accepted Solution

A:

Answer:65.8 in²Step-by-step explanation:Given a triangle with 2 sides and the included angle then the area (A) isA = 0.5 × a × b × sinΘwhere a, b are the 2 sides and Θ the included anglehere a = 18, b = 12 and Θ = 147°, henceA = 0. 5 × 18 × 12 × sin147° = 108 × sin147° ≈ 65.8 ( to the nearest tenth )
