Answer:

here's your answer

Answer 2

Answer:

The length of third side is 13 cm.

Step-by-step explanation:

• Let us assume the first two sides of triangle be ‘a’ and ‘b' and the third side be ‘c’ .

• Now the sum of two sides is given 17 cm,

Therefore , a + b = 17.

• Perimeter of triangle = 30 cm

a + b + c = 30 cm

17 + c = 30 cm

= 30 - 17

c = 13 cm.
