Answer:
x = 80
Step-by-step explanation:
In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360
115 + 95 + 70 + x = 360 just add the like terms
280 + x = 360 now subtract 280 from both sides so x is alone and you can figure out its value
x= 80
