Answer 2

Answer:

Two equal sides of triangle are 20 and third side is 10

Step-by-step explanation:

Let two equal sides be x and third side be y.

According to question:-

x=2y ......................... equation 1

perimeter of triangle=sum of all sides of triangle

50=x+x+y

50=2y+2y+y(x=2y from equation 1)

50=5y

50/5=y

y=10

Putting value of y in equation 1

x=2y

x=2×10

x=20
