X=10 because. (X-3)=-49. so (10-3) with the power of 2=-49
First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10
X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90
Hello! Draw a hundred (I know, it's tedious!) circles. Make a giant bracket around them all and label it "One Whole". Then color in 51 of those circles.
I hope this helps!
Answer:
it was right but ok
Step-by-step explanation:

6th graders : total
4 : 18
Divide each side by 2
4/2: 18/2
2 : 9
