The angles of a polygon are given by 2x, 5x, x and 4x respectively. The value of x is
-
A.
31° -
B.
30° -
C.
26° -
D.
48°
Correct Answer: Option B
Explanation
Since there are 4 angles given, the polygon is a quadrilateral.
Sum of angle in a quadrilateral = 360°
(therefore) 2x + 5x + x + 4x = 360°
12x = 360°
x = 30°
