Answer:
x = 300 feet
Explanation:
In the given right triangle,
Length of the string of the kite = 324 feet
Angle between the string and the ground = 68°
By applying law of Sines in the given right triangle,
![\frac{\text{SinA}}{a}=\frac{\text{SinB}}{b}=\frac{\text{SinC}}{c}](https://img.qammunity.org/2021/formulas/mathematics/high-school/cqhcrziyenh712eshxlenp4ssm56576umm.png)
Now we substitute the values of angles and sides in the formula,
![\frac{\text{Sin68}}{x}=\frac{\text{Sin90}}{324}](https://img.qammunity.org/2021/formulas/mathematics/college/lntvt9rtir6t3u8homa3rv7bwwbwchei1a.png)
![\frac{\text{Sin68}}{x}=(1)/(324)](https://img.qammunity.org/2021/formulas/mathematics/college/r0vdx0363z5s9t5ekdj0a5it72cbrfofm3.png)
x = 324 × Sin(68)°
x = 300.41 feet
x ≈ 300 feet
Therefore, measure of side x = 300 feet will be the answer.
