The diagram is a polygon. Find the largest of its interior angles
Attached Figure / Diagram
A
300o
B
100o
C
120o
D
150o
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Sum of interior angles = 3602
i.e 3x + 2x + 2x + x + 4x = 360o
12x = 360
x = \(\frac{360}{12}\)
x = 30o
x + c = 180
30o + c = 180
c = 180 - 30
c = 150o
