Question

two equal sides of a triangle are each 5meter less than twice the third side if the perimeter of the traingle is 55 meter find the length of its side

Answer 1

Answer:

Third side = 13m

other two sides = 21m

Step-by-step explanation:

Third side = x

First and second side = 2x-5

Perimeter= 55m

Perimeter of a triangle= side + side + side

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

55 = 5x - 10

5x = 55+10

X = 65/5

x = 13

Third side = 13m

First and second side = (2X13)-5 = 26 - 5 = 21m

Answer 2

Answer:

Third side 13

Other two sides 22
