Question

Sides of a quadrilateral are all positive integers . Three of them are 5,10,20 . How many possible values are there for the fourth side?

Answer 1

length of the fourth side must be less then the sum of the other three sides
x < 5+10+20
x<35

so 1≤x<35
there are 35 possible values

Answer 2

u r wrong

Answer 3

why

Answer 4

it's between 5 and 35

Answer 5

as you can see, the side that's 5 and 10 can rotate to get those values of 5 and 35.
