Answer:</h2>
<u>x= 90°</u>.
<h2>
Step-by-step explanation:</h2>
<h3>1. Write the expression.</h3>

<h3>2. Subtract "4" from both sides of the equation.</h3>

<h3>3. Add "8sin(x)" to both sides of the equation.</h3>

<h3>4. Divide both sides by 10.</h3>

<h3>5. Apply the arcsin of sin^-1 to both sides of the equation.</h3>

<h3>6. Conclude.</h3>
<u>x= 90°</u>.
