In fig., lines l and m intersect each other at O. If x = 40o then, find the value of y, z and w.

x = 40o z = x (vertically opposite angles)

z = 40o

xo + yo = 180o

40o + yo = 180o

y = 140o

Again x o + w o = 180o

40o + w o = 180o w o = 140o

Thus y = w = 140o, z = 40o

A graph may be defined as a set of points connected by lines called edges. Every edge connects a pair of points. Thus a triangle with 3 edge and 3 points. The degree of a point is the number of the edges connected to it. For example, a triangle is a graph with 3 points of degree 2 each. Consider a graph with 12 points. It is possible to reach from any other point through a sequence of edges. The number of edges, e, in the graph must satisfy the condition:- a) 11 ≤ e ≤ 66 b) 11 ≤ e ≤ 65 c) 10 ≤ e ≤ 66 d) 0 ≤ e ≤ 11
