In triangle ABC, a = 4, B = 1. Angle c equals 45 degrees. What is the area of triangle ABC

In triangle ABC, a = 4, B = 1. Angle c equals 45 degrees. What is the area of triangle ABC

Triangle area formula s = (1 / 2) × a × B × sin ∠ C (both sides and angle of triangle)
S △ ABC = (1 / 2) × 4 × 1 × sin45 ° = √ 2 (root 2)
