Answer:
y= -8x + 150
x = -0.125y + 18.75
Step-by-step explanation:
<u>y explanation:</u>
16x+2y=300
Add -16x to both sides: 16x+2y+(-)16x = 300 + (-)16x - this becomes:
2y = -16x+300
Now divide both sides by 2: 2y/2 = (-16x+300)/2 - this becomes:
-8x + 150
So...y= -8x+150
<u>x explanation:</u>
16x+2y = 300
Add -2y to both sides: 16x+2y+(-)2y = 300+(-)2y - this becomes:
16x = -2y+300
Now divide both sides by 16: 16x/16 = (-2y+300)/16 - this becomes:
-1/8y + 75/4...you can simplify this to: -0.125y + 18.75
So...x = -0.125y + 18.75
I hope this helps :)
Answer:
x = 36.9°
Step-by-step explanation:
We need to find out what sides of the triangle we have, <em>so we can find the formula for the missing angle, x.</em>
We have been given the <em>opposite</em> and <em>hypotenuse</em> so we are using sine
SOH, CAH, TOA
sin (x) = opp ÷ hyp
<em>Substitute in the values</em>
sin (x) = 9 ÷ 15
<em>Simplify</em>
sin (x) = 0.6
<em>Rearrange to find x</em>
x = sin^-1(0.6) - Type this into your calculator
<h3>
sin^-1 is the inverse or opposite of sin</h3>
x = 36.8698... ≈ 36.9°
