Correct Answer: Option A

Explanation

From the diagram above, a = 180º - 85º - 45º = 50º ( sum of <s on a straight line)

b = 50º( vertically opp. <s)

85º = c + 34º ( corresponding <s), so c = 85º - 34º = 51º

d = 180º - 50º - 51º = 79º ( sum of <s in a triangle)

x = 360º - 79º = 281º ( <s at a point)
