Question

The sides of a quadrilateral are all positive integers and three of them are 5, 10, 20. How many possible values are there for the fourth side?​

Answer 1

Step-by-step explanation:

For first triangle. Let take the unknown side be x.

X maish be less than 10 + 20.

Max value of x=29

2. For second Triangle X must be any side of the triangle and the third side of the quadrilateral any side(5)So X + 5 is greater than fourth side which implies( putting X equals to 29). We get that the fourth side must be less than 34. So it can take zero to 34 values excluding (zero and 34)

Answer…

So the answer is 32
