One interior angle of a convex hexagon is 170o and each of the remaining interior angles is equal to xo. Find x
-
A.
120o -
B.
110o -
C.
105o -
D.
102o -
E.
100o
Correct Answer: Option B
Explanation
An hexagon polygon is a six sided polygon
n = 6
sum of all interior angles of hexagon polygon will be (2n – 4) x 90o
= [2 x 6 – 4] x 90
= 720o
If one angle is 170o and each of the remaining five angles is 5xo
5xo + 170o = 720o
= 5x + 550
x = (frac{550}{5})
= 110o
