Question

Each of the two equal sides of a triangle are 4m lest then three times the third side find the dimensions of the triangle, if its perimeter is 55m

Answer 1

Answer:

9 , 23 , 23

Step-by-step explanation:

Let the third side be x

So , the 2 equal sides will be 3x-4 and 3x-4

∴ Perimeter = sum of all sides

∴ 55 = x +3x-4 +3x-4

∴ 55 = 7x-8

∴ 63 = 7x

∴ x = 9

∴ The sides are  :  9 , 23 , 23
