Answer:
Your answer is B
Step-by-step explanation:
There are 3 kids ages 9-10, so that's the first 3.
There are 10 kids ages 10-11, so that's the second 10.
There are 6 kids ages 11-12, so that's the third 6.
add those kids up and you get 19
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.
