Question

The perimeter of an isosceles triangle is 43/4cm if one of its equal sides is 17/ 6 cm find the third side

Answer 1

Answer:

Let the thee sides be a=17/6 b=17/6 c.

A/Q,

a+b+c=43/4cm

c=43/4-(a+b)

=43/4-(17/6+17/6)

=43/4-34/6

=129-68/12=61/12

c=61/12

Answer 2

given in triangle ABC

perimeter=43/4cm

AB=BC=17/6

We know,

perimeter=43/4

AB+BC+AC=43/4

17/6 + 17/6 +AC= 43/4

(17+17)/6 + AC= 43/4

34/6 + AC= 43/4

AC=43/4 - 34/6

AC=(258-136)/24

AC=122/24

AC=61/12

AC=5.083

the third side is 5.083
