Question 351723: A banner in the shape of an isosceles triangle has a base that is 5 inches shorter than either of the equal sides. If the perimeter of the banner is 37 inches, then what is the length of the equal sides? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! B=S-5
2S+B=37
2S+(S-5)=37
3S=37+5
3S=42
S=42/3
S=14 INCHES FOR THE EQUAL SIDES.
B=14-5=9 INCHES FOR THE BASE.
PROOF:
2*14+9=34
28+9=37
37=37
