since it is a quadrilateral, all the sides will add to 360. If two angles are 90, and one is 99, add them and subtract from 360. The last angle should be 81 degrees.

Answer:
x = 16
Step-by-step explanation:
The probability of obtaining a green ball is
P(green) =
=
and
P(green) =
, hence equating gives
=
( cross- multiply )
2(x + 14) = 60 ( divide both sides by 2 )
x + 14 = 30 ( subtract 14 from both sides )
x = 16
