In the diagram PQ and MN are straight lines. Find the value of x

In the diagram PQ and MN are straight lines. Find the value of x

A.
13^o
B.
17^o
C.
28^o
D.
30^o

Correct Answer: Option B

Explanation

The straight line MN = 180 = 2(x+30^o) + 86^o =>
180 = 2x + 60^o + 86^o => 180^o = 2x + 146^o => 2x = 180 – 46 = 34^o => x = 34/2 = 17^o
