Question

Each of two equal sides of a triangle is 3cm less than twice the third side. If the perimeter of the triangle is 69, find the lengths of its sides.

Answer 1

Answer:

Step-by-step explanation:

equal sides = a cm

other side =l cm

atq,  a-3=2l

         a=2l+3

a+a+l=69

2(2l+3)+l=69

5l=63

l=12.6cm

a=28.2cm
