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.

Answer:
The three consecutive integers are 42,44 and 46
Step-by-step explanation:
n-2 n and n+2. n=44
or
(X) + (X + 1) + (X + 2) = 132
X + X + 1 + X + 2 = 132
3X + 3 = 132
3X + 3 - 3 = 132 - 3
3X = 129
3X/3 = 129/3
X = 43
43 + 44 + 45 = 132

For the given question above, if the cos <span>30Á = square root 3 over 2, then the sin 60Á = square root over 2. Square root over 2 is the correct answer because they are just complimentary. I hope this answer helps. Looking forward to help you again.</span>
The smallest possible sum is the sum of the two square roots, 6 + 6 = 12.
