The angles marked in the figure are measured in degrees. Find x.
-
A.
45o -
B.
90o -
C.
60o -
D.
15o -
E.
30o
Correct Answer: Option E
Explanation
Sum of external angles = 360o
3x + 5x + x + 2x + x = 360o
12x = 360o
x = 30o
Sum of external angles = 360o
3x + 5x + x + 2x + x = 360o
12x = 360o
x = 30o
