Find the area of the triangle. Round your answer to the nearest tenth. Triangle ABC line AB = 41 in., line AC = 41 in., ∠A=38°

a. 840.5 in. 2 b. 1,034.9 in. 2 c. 656.7 in. 2 d. 517.5 in. 2

A = 517.5 in.² ⇒ answer (d)

Step-by-step explanation:

∵ The area of any triangle with given two sides and including angle is

A = 1/2 * side1 * side2 * sin including angle

∵ AB = 41, AC = 41 and angle A = 38°

∴ A = 1/2 * 41 * 41 * sin 38 = 517.5 in.² ⇒ answer (d)
