Question

10. Each side of an isosceles triangle is 15 cm and perimeter of the triangle is 50 cm. Find the
third side.​

Answer 1

Answer:

20 cm

Step-by-step explanation:

if it is isosceles triangle then two sides are equal to each other so

15*2=30

And perimeter is 50 then third side will be 50-30=20.

Answer 2

Answer:

20cm

Step-by-step explanation:

Length of one side = 15cm

Length of opposite side = 15cm

(isosceles property)

Perimeter = 50cm

Let the third side be x.

ATQ

15cm + 15cm + x = 50cm

=) 30cm + x = 50cm

=) x = 50cm - 30cm = 20cm

Hence, the third side is 20cm.
