Question

The perimeter of an isoceles tringle is 43/4 cm. if one of its equal side is 17/6 cm find the third side

Answer 1

perimeter of an isosceles triangle is 43/4 cm.
one of its equal sides is 17/6 cm, then the second equal side will also be 17/6 cm.
Third side=perimeter - 2*length of one side=43/4 -34/6 = (129–68)/12 = 61/12 cm.

Answer 2

Answer:

$\frac{61}{12}$

Step-by-step explanation:

Given :The perimeter of an isosceles triangle is 43/4 cm.

To Find: if one of its equal side is 17/6 cm find the third side

Solution:

We are given that one of equal sides of isosceles triangle is 17/6

Let the third side be x

So,Perimeter of triangle = $\frac{17}{6} +\frac{17}{6} +x$

We are also given that The perimeter of an isosceles triangle is 43/4 cm.

So,$\frac{43}{4}=\frac{17}{6} +\frac{17}{6} +x$

$\frac{43}{4}-\frac{17}{3} =x$

$\frac{61}{12} =x$

Hence the third side is $\frac{61}{12}$
