Question 829408: The base of an isosceles triangle is 26 cm. If the perimeter is 72 cm. find the lenght of each of the equal sides. Answer by rm29924(97) (Show Source):
You can put this solution on YOUR website! An isosceles triangle has two equal sides.
We know the base = 26 cm.
x + x + 26 = 72 cm
combine like terms, the xs
2x + 26 = 72 cm
subtract 26 from both sides
2x=46
divide both sides by 2 to get the x by itself
x=23
The length of the equal sides is 23 cm.
check your answer: 23+23+26=72
72=72
