Question

Find the area of the triangle. Round your answer to the nearest tenth. Triangle ABC Line AB =15 yd, Line AC = 15 yd, ∠A= 48° a. 112.5 yd2 b. 167.2 yd2 c. 124.9 yd2 d. 83.6 yd2

Answer 1

A = 83.6 yd² ⇒ answer (d)

Explanation:

∵ AB = 15 , AC = 15 and m∠A = 48°

∵ Area of the Δ by using sin Rule

∴ A = 1/2 × S1 × S2 × sin including angle between two sides

∴ A = 1/2 × 15 × 15 × sin48 = 83.6 yd² ⇒ answer (d)
