<h2>
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>.
Yes because 1500/60 = 25 which is the number of words per minute. He has 5 minutes to text so 25 x 5 = 125. In 5 minutes he can type 125 words
<h3>
Answer: 35.54 degrees</h3>
How I got this answer:
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 5/7
A = arctan(5/7) .... apply the inverse tangent, same as arctangent
A = 35.5376778 ... make sure your calculator is in degree mode
A = 35.54 .... rounding to two decimal places
