Answer:
The correct answer is option B). 108°
Step-by-step explanation:
Points to remember
Sum of angles of hexagon is 720°
From the figure we can see a hexagon.
To find the m<B
m<B = 720 - ( m<A + m< C + m<D + m<E + m<F)
= 720 - ( 170 + 133 + 102 + 117 + 90)
= 720 - 612
= 108°
Therefore m<B = 108° Option B is the correct answer
