Question

Two equal sides of a triangle are each 5meter less than twice the third side . If the perimeter of a triangle is 55meters , find the length of its side

Answer 1

Answer:

Step-by-step explanation: let one side of the triangle be ‘x’. Hence, the other two sides are = (2x-5)m

=> perimeter = 55m= x+ 2(2x-5)

= x+4x-10

=5x-10

55=5x-10

(Divide the entire equation by 5)

11=x-2

Hence,

x=11+2

=13m
