Answer:

2 $\frac{1}{3}$ inches

Step-by-step explanation:

First, I would try to get the mixed numbers into improper fractions. Then, I try to make them have the same denominator so it is easier.

1 $\frac{1}{2}$ feet --- 2 inches

$\frac{3}{2}$ feet --- 2 inches

$\frac{6}{4}$ feet --- 2 inches

1 $\frac{3}{4}$ feet --- ? inches

$\frac{7}{4}$ feet --- ? inches

$\frac{7}{4}$ feet --- $\frac{7}{6}$ × 2 inches

= 2 $\frac{1}{3}$ inches

Alexus [3.1K]

Answer: Approximately 8.49 feet

==================================================

Explanation:

Draw a right triangle. The reference angle is between the ground and the kite string (aka hypotenuse). The hypotenuse is 12 and the side opposite the reference angle is x.

Refer to the diagram below.

We'll use the sine rule to find x

sin(angle) = opposite/hypotenuse

sin(45) = x/12

12*sin(45) = x

x = 12*sin(45)

x = 8.48528137423857

x = 8.49

This value is approximate.

Make sure your calculator is in degree mode.

I rounded to 2 decimal places, but feel free to round however you need if your teacher instructs otherwise.
