The Third Side Is Called The base if an isosceles triangle has perimeter 345 cm and base length 85 cm what is the length of each
maks197457 [2]

Answer:

Length of each leg = 130 cm.

Step-by-step explanation:

Given that there is an isosceles triangle which has perimeter 345 cm.

Base length =85 cm.

Since other two sides are equal, let the equal size = x

Perimeter = sum of all 3 sides of a triangle

= 85+x+x = 85+2x

But perimeter = 345 (given)

So equate x term perimeter with actual

85+2x = 345

Subtract 85

2x = 260

Divide by 2

x =130 cm.

Hence answer is 130 cm.
