Question

the perimeter of an isosceles triangle is 10 3 / 4 centimetre if once it equal side is 2 5/6 cM find side​

Answer 1

Answer :-

15 1/4 cm.

Step-by-step explanation:

Let, the third side be x

Perimeter of the triangle = 10 3/4 cm

Length of one equal side = 2 5/6 cm

Then, length of the other equal side = 2 5/6 cm

Length of the third (unequal) side =

x + 2 5/6 + 2 5/6 = 10 3/4

=) x + 34/6 = 43/4

=) x = 43/4 - 34/6

=) x = 61/4

=) x = 15 1/4 cm

Hence, the length of the third side is 15 1/4 cm.
