Answer 2

Answer:

The sides of traingle are of 9m, 23m and 23m

Step-by-step explanation:

Let x be the third side,

Then (3x−4) will be length of the equal sides.

As per the question-

55=x+2(3x−4)

55=x+6x−8

55=7x−8

55+8=7x

63=7x

9=x

Therefore, the third side = x=9m.

Hence, the equal two sides = (3x−4)=(3×9−4)=27−4=23m each.
