Answer:
x = 15°
Step-by-step explanation:
First Identify the angle of x by subtracting 180° - 120° = 60°
Always remember when you see a straight line the line measures 180°
So the angle of x = 60° but not the value of x so use the given equation to find the value of x
3x + 15 = 60°
3x - 15 = -15°
3x = 45
x = 15°
Answer:
b. you sold 17
c. your friend sold 25
Step-by-step explanation:
you=y your friend=x
y=x-8
42=x +y
42=x+(x-8)
42=x+x-8
42=2x-8
50=2x
25=x
Use x to solve for y...
y=25-8
y=17
128 inches
for area , you multiply length times height so it’d be 16 x 8 :)
Hi there!
mistake= step 2..
If you can see, the equation is the opposite so this means that to find the answer, your gonna have to add first.. instead of subtracting..
<em><u>1.Add the terms:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>2.Simplifly the terms:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>3.Subtract the terms:</u></em>
<em><u /></em>
<em><u /></em>
Therefore, the mistake was step 2...
