To the nearest square inch, how much fabric will she use to make all three triangles? 139 square inches 172 square inches 417 sq
1 answer:
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:
<h3>5 years</h3>Step-by-step explanation:
To get the median of the ages given
2, 4, 5, 6, 7, 8, 8, 8, 0, 3, 5, 9, 1, 4, 7, 6, 1, 2, 4, 4, 8
First we will need to rearrange the median ages in ascending order (from lowest to highest)
0, 1, 1, 2, 2, 3, 4, 4, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8, 8, 9
Next is to locate the middle value of the arranged data
(0, 1, 1, 2, 2, 3, 4, 4, 4, 4), 5, (5, 6, 6, 7, 7, 8, 8, 8, 8, 9)
The total values in both parenthesis are the same(10 in numbers) leaving 5 as the middle number.
Hence the median age of the people in the pool is 5years
