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

hiii!!!

here's ur answer...

given that one of the equal side of the isosceles triangle is 17/6cm.

therefore the another equal side is also 17/6cm.

let the third side be c and the two equal sides be a and b.

perimeter of the isosceles triangle = 43/4cm

therefore a + b + c = 43/4cm

==> 17/6 + 17/6 + c = 43/4cm

==> 34/6 + c = 43/4cm

==> c = 43/4 - 34/6

==> c = 129/12 - 68/12

==> c = 61/12cm

hence 3rd side is 61/12cm.

hope this helps..!!

Answer 2

Given that two sides are equal and those lengths are 17/6 and 17/6.
perimeter is sum of all sides.
Therefore (2*(17/6))+third side=43/4
third side=43/4 -17/3=61/12
