Answer:

13

Step-by-step explanation:

Use sin = opposite/hypotenuse

Setup an equation. I'm going to use x to represent the hypotenuse.

[tex]sin44=\frac{9}{x}[/tex]

Now move the x to the other side by multiplying. We want to solve for x.

[tex]x(sin44)=(\frac{9}{x})x[/tex]

The x cancels on the right side. Now divide both sides by sin44. To get  by itself on the left.

[tex]\frac{x(sin44)}{sin44} = \frac{9}{sin44}[/tex]

[tex]x = \frac{9}{sin44}[/tex]

Use your scientific calculator, make sure it is on degrees, and divide 9 by sin44.

[tex]x = 12.9560088566[/tex]

Round to the nearest whole number

[tex]x = 13[/tex]
