need help solving this problem. having trouble because I don't understand

Answer:
x = 95.1
Explanation:
To find the value of x, we will use the trigonometric function sine because:
[tex]\begin{gathered} \sin 72=\frac{Opposite}{Hypotenuse} \\ \sin 72=\frac{x}{100} \end{gathered}[/tex]Now, we can solve the equation for x as:
[tex]\begin{gathered} 100\cdot\sin 72=100\cdot\frac{x}{100} \\ 100\cdot(0.951)=x \\ 95.1\text{ m = x} \end{gathered}[/tex]Then, the value of x is 95.1 m
