A)10 m , 10m , 40 m
B)15 m , 15 m , 30 m
C)20 m , 20 m , 20 m
D)5 m , 15 m , 40 m
WITH EXPLAINATION

Answer 1

Answer:

option (b) 15m,15m,30m

Answer 2

Answer:

In a isosceles triangle 2 sides will equal

Therefore correct answer is 15m, 15m, 30 m

Because most of the isosceles triangle are right triangle

Hence by pythagoras theorem Square of hypotenuse = Square of other 2 sides

So ans = B)
