Solve for x. NEED HELP
TiliK225 [7]

Answer:

22.470

Step-by-step explanation:

In this example you have to use the trigonometric function sine which is defined as sin(\theta) = \frac{opposite}{hypotenuse}

Plug in known values:

sin(64) = \frac{x}{25}

Multiply both sides by 25

sin(64) * 25 = x

Approximate sin(64) using a calculator:

0.89879 * 25 = x

Simplify

22.470 \approx x
