two equal sides is 18cm, Find the third side.
​

Answer 1

Answer:

14

Step-by-step explanation:

Let, the triangle be △ABC

Given, AB=CA=18 cm

Perimeter of the △ABC=50 cm

⇒AB+BC+CA=50 cm

⇒18 cm+BC+18 cm=50 cm

⇒BC=50 cm−36 cm=14 cm

Hence, Third side BC=14 cm

Answer 2

Answer:

third side = 14cm

Step-by-step explanation:

50= 18+18+ third side

third side = 50-36

third side = 14 cm
