If three angles of a quadrilateral are (3y - x - z)o, 3xo, (2z - 2y - x)o find the fourth angle in terms of x, y and z
Answer Details
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
