In the figure, POR and QOR form a linear pair. If b - a = 60°, find the value of a and b.

POQ is a straight line

b-a = 60O (given) …..(i)

a+b = 1800 (linear pair axiom) …..(ii)

Adding (i) and (ii)

2b = 2400

b= 1200

Equation (i) gives a = b - 60o = 120o-60o= 600

Hence, a = 600 and b = 1200

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
