Applying the trigonometric area formula, the amount of fabric she will need to make all the three triangles is: C. 417 square inches.

<h3>What is the Trigonometric Area Formula?</h3>

The trigonometric area formula is expressed as: Area = 1/2 × ab × sin(C).

Find the area of one of the triangles:

a = 17 in.

b = 17 in.

C = 74°

Area = 1/2 × (17)(17) × sin(74) ≈ 139 sq. in.

Area of the three triangles = 3(139) = 417 square inches.
