Please help !! Geometry homework. Will mark brainliest answer !

Answer 1

For this case we have:

By trigonometric property we have:

$Sin\alpha=\frac{opposite leg}{hypotenuse}$

Where:

$opposite leg = x$

$hypotenuse = 8\\\alpha= 70 degrees$

Substituting: $Sin70 = \frac{x}{8}$

Clearing x we have: $x = 8 * sin70$

Thus, the equation is:$x = 8 * sin70$

Answer:

$x = 8 * sin70$
