Answer:

Step-by-step explanation:

Answer 2

Answer:

The one equal side of triangle = 21m

The other equal side of triangle = 21m

The third side  = 13m

Step-by-step explanation:

Let the  one equal side of triangle = 2x-5

Let the other equal side of triangle = 2x-5

Let the third side = x

So,

According to the question:-

x+2x-5+2x-5 = 55

=>5x -10 = 55

=> 5x = 65

=> x = 13

Hence,

The one equal side of triangle = 2x-5 = 2*13-5 = 21m

The other equal side of triangle = 2x-5 = 2*13-5 = 21m

The third side = x = 13m
