Question

The length of the congruent sides of an isosceles triangle is 5 less than thrice the length of its base. Write the equation for this statement using two variables.​

Answer 1

Answer:

the length of sides are 7 cm,7 cm and 10 cm.

Step-by-step explanation:

Let the length of the base of an isosceles triangle be x cm.

Therefore, as per the given conditions,

Therefore, as per the given conditions,Length of the congruent sides =2x−13 cm

, as per the given conditions,Length of the congruent sides =2x−13 cm Given, the perimeter of an isosceles triangle =24 cm.

cmCongruent sides =2x−13=2×10−13=20−13=7 cm

Therefore, the length of sides are 7 cm,7 cm and 10 cm.
