Question

the perimeter of an isosceles triangle is 59 CM.if the base is 23 CM, find the length of the equal sides​

Answer 1

Perimeter of an isosceles triangle is,

Base + 2[Equal Sides(X)]

= 23 + 2(X) = 59

2X = 59-23 = 36

X = 18

Thus, length of the equal sides is 18cm

Answer 2

Answer:

let x be the other two sides then,

x+x+23=59(because in triangle sum of three sides is perimeter)

2x+23=59

2x=59-23

2x=36

x=36/2

x=18

then sides are 18cm
