In figure, if x : y = 3 : 7, then find the value of x,y,z and w.

answered-by-expert Expert Answer

x : y = 3 : 7

3a + 7a = 180

10a = 180

a = 18o

Thus, x = 54, y = 126

Since vertically opp. Angles are equal, therefore

y = w = 126o

x = z = 54o

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
