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.
