Answer:
he will need 224 yards of string
Step-by-step explanation:
56 ballons *12 feet=672 feet
each yard is 3 feet so he will need
1yard--->3feet
X<-------672feet=224 yards

B :81 EXPLANATION
The angle with the greatest measure corresponds to the longest:
Since we know the three side lengths, we use the cosine rule to obtain;
{a}^{2} = {b}^{2} + {c}^{2} - 2bc \cos(A)
where a=21, b=18 and c=14
{21}^{2} = {18}^{2} + {14}^{2} - 2 \times 18 \times 14\cos(A)
44 1= 324+ 196 - 504\cos(A)
44 1= 520 - 504\cos(A)
44 1 - 520 = - 504\cos(A)
- 79 = - 504\cos(A)
\cos(A) = 0.1567
A = \cos ^{ - 1} (0.1567) = 80.98 \degree

- SOHCAHTOA
- [Right Triangles Only] sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing length.
<u>Step 2: Identify Variables</u>
Angle = 31°
Opposite = 19
Hypotenuse = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: sin31° = 19/x
- Multiply <em>x</em> on both sides: xsin31° = 19
- Isolate <em>x</em>: x = 19/sin31°
- Evaluate: x = 36.8905
- Round: x ≈ 36.9
