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 Option: Answer is B

Solution:
Since there are 4 angles given, the polygon is a quadrilateral.
Sum of angle in a quadrilateral = 360°
∴ 2x + 5x + x + 4x = 360°
12x = 360°
x = 30°
