Question

Two equal sides of an isosceles triangle are each 3m less than thrice the third side. If the perimeter of the triangle is 123. Then,write the equation in linear equation in one variable to solve for the sides of the triangle

Answer 1

Step-by-step explanation:

Let the unequal side be x.

According to the question,

The equal sides= 3x-3

Perimeter= 123m

Now, (3x-3)+(3x-3)+x=123 (Equation you want)

=> 7x-6=123

=> 7x=129

=> x=18.52

Rest you can figure out.

Answer 2

this answer is very easy

Step-by-step explanation:

there , it is said that equal sides = 3×-3

perimeter is = 123

(3×-3)+(3×-3)+×=123

= 7×-6=123

=7×=129

=×=18.52
