(360 - x- y - z)o
(360 + x + y - z)o
(180 - x + y + z)o
(180 - x + y + z)o
Correct answer is A
The sum of angles of a quadrilateral is 360o
∴ (3y - x - z)o + 3xo + (2z - 2y - x)o + po = 360o
Where P is the fourth angle
3y - x - z + 3x + 2z - 2y - x + p = 360o
p = 360 - (x + y + z)
∴ p = (360 - x - y - z)o
