Find the sides of a triangle if two of its sides are equal, the third side is 1 1/3 cm longer than the others, and its perimeter is 5 2/5 cm. Two equal sides of the triangle are cm. The third side is.

Length oh two equal sides: 1 16/45 cm

Third side: 2 31/45 cm

Step-by-step explanation:

length of two equal sides is x

Perimeter = x + x + (x + 1 1/3) = 3x + 1 1/3 = 5 2/5

3x = 5 2/5 - 1 1/3 = 27/5 - 4/3 = 61/15

x = 61/45 = 1 16/45

Third side = 61/45 + 4/3 = 121/45 = 2 31/45
