a)120
b)199
c)125
d)190​

Answer 1

Step-by-step explanation:

Given The sides of quadrilateral are all positive integers and three of them are 30 80 90 units how many possible values are there for the fourth side

From the property of quadrilateral, sum of all sides of quadrilateral will be greater than 4 th side.

Now maximum length will be  

30 + 80 + 90 – 1 = 199

Also let minimum length be x

So 90 = 80 + 30 + x

Therefore x = 20

So from 20 to 199 integers can be 199 – 20 = 179
