12 divided by sin(60) equals to 8square root 3
Archy [21]3 years ago

Answer:

8\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and

sin60° = \frac{\sqrt{3} }{2}

sin60° = \frac{opposite}{hypotenuse} = \frac{12}{y}

Multiply both sides by y

y × sin60° = 12, that is

y × \frac{\sqrt{3} }{2} = 12 ← multiply both sides by 2

y × \sqrt{3} = 24 ( divide both sides by \sqrt{3})

y = \frac{24}{\sqrt{3} }

  = \frac{24}{\sqrt{3} } × \frac{\sqrt{3} }{\sqrt{3} }

  = \frac{24\sqrt{3} }{3} = 8\sqrt{3}
