Find the value of x in the diagram
A
50o
B
30o
C
22o
D
17o
correct option: d
Sum of exterior angles of a polygon = 360o
(x + 64) + 2x + (3x - 54) + 5x + 4x + 3x + (2x + 10) = 360o
20x + 20 = 360o
20x + 360 - 20 = 340o
x = \(\frac{340}{20}\)
x = 17o
(x + 64) + 2x + (3x - 54) + 5x + 4x + 3x + (2x + 10) = 360o
20x + 20 = 360o
20x + 360 - 20 = 340o
x = \(\frac{340}{20}\)
x = 17o
