Question

each of two equal side of a triangle are 4 m less than three time the third side.
Find the dimensions of the triangle, if it's perimeter is 55 m

it's answer is
side of triangle are 23 m, 23 m and 9 m

Answer 1

HELLO DEAR,


LET THE THIRD SIDE BE X METER.

EACH TO SIDE BE (3X-4)


GIVEN THAT:-

55=X+2(3X-4)


55=X+6X-8


7X=63

X=9

=>(3×9-4)=23

I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

HEYA!!!!

Given,

perimeter of triangle = 55 cm

Each of 2 equal side of a triangle are 4 less than the three time the third time.

Hence,

let the third side be " x "

Then the two sides = ( 3x-4)

Perimeter of isosceles triangle = sum of all three sides.

ATP,

55 = x + 2 ( 3x-4)

55 = x + 6x - 8

63 = 7x

x = 63/7

x = 9..

Therefore, the sides are 3x - 4 = 3 ( 9 ) - 4 = 23..
