Answer:
Step-by-step explanation:
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
