Question

*The equal sides of an isosceles triangle are 5 units less than twice the third side. What is the length of equal sides of the triangle, provided its perimeter is 75 units .

Answer 1

Answer:

Length of equal sides of the triangle is 29

Step-by-step explanation:

Given perimeter is 75

let third side be a

two equal sides of isosceles be 2a-5

2a-5+2a-5+a=75

5a-10=75

5a=85

a=17

length of equal isosceles sides are 2a-5 =2(17)-5

= 29
