isosceles triangle: base 3cm longer than each of the equal legs
Let x be the length of each side of the isosceles triangle
x + x + (x+3) = 36cm
3x = 33cm
x = 11cm, the length of each side of the isosceles triangle
base is 14cm
And... checking
11cm + 11cm + 14cm = 36cm
Wish You the Best in your Studies.
