Answer:
22.470
Step-by-step explanation:
In this example you have to use the trigonometric function sine which is defined as [tex]sin(\theta) = \frac{opposite}{hypotenuse}[/tex]
Plug in known values:
[tex]sin(64) = \frac{x}{25}[/tex]
Multiply both sides by 25
[tex]sin(64) * 25 = x[/tex]
Approximate sin(64) using a calculator:
[tex]0.89879 * 25 = x[/tex]
Simplify
[tex]22.470 \approx x[/tex]
