12 divided by sin(60) equals to 8square root 3
Archy [21]3 years ago
5 0

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}

Solve the system of equations.<br> y= 3x +5<br> y= 8x +3
Lady bird [3.3K]

Answer:

y=6.2 and x=0.4 or (0.4,6.2)

Step-by-step explanation:

Since both expressions are equal to y, we can set them equal to each other and solve for x:

3x+5=8x+3

5=5x+3

2=5x

2/5=x

0.4=x

Now to solve y:

y=8(2/5)+3

y=16/5+3

y=3.2+3

y=6.2

Check answers:

6.2=3(0.4)+5

6.2=1.2+5

6.2=6.2

6.2=8(0.4)+3

6.2=3.2+3

6.2=6.2

Answers work, so y=6.2 and x=0.4 or (0.4,6.2) as an ordered pair
