Question

A.120
B.199
C.125
D.190​

Answer 1

Answer:

199

Step-by-step explanation:

if the sides of a quadrilateral are all positive integers and three of them are 30, 80 and 90 units then there are 199 possible values for the fourth side

This is because that the length of the fourth side of a quadrilateral cannot be equal to or greater than the sum of the length of other three sides.

30+80+90=200

The length of fourth side has to be less than 200

199 is the correct answer.
