Answer:

x = 5√3

Step-by-step explanation:

From SOHCAHTOA you might recall that sin x = opposite/hypotenuse

So sin 60° = x/10

sin 60° = 0.5 √3

so x = 10*0.5√3 = 5√3

Answer:

sin\alpha=opposite/hypotenuse\\\\sin60=\frac{x}{10}\\ \\\frac{\sqrt{3}}{2}=\frac{x}{10}\\  \\2x=10\sqrt{3}\\ \\x=\frac{10\sqrt{3}}{2}\\ \\x=5\sqrt{3}
