Question

A triangle has a perimeter of 200. If two of its sides are equal and the third side is 20 more than the

equal sides, what is the length of the third side?​

Answer 1

Answer:

Step-by-step explanation:

let the equal sides = x

then let third side be x+20

therefor

x+x+x+20 = 200

3x + 20 =200

3× = 200 - 20

3× = 180

× = 60

so length of third side is 80
