Q8 of 115 Page 8

In Fig. 8.37, determine the value of x.

Sum of all the angles around the point = 360^o

3x + 3x + 150^o + x = 360^o

7x = 360^o – 150^o

7x = 210^o

x = 30^o

How many pairs of adjacent angles are formed when two lines intersect in a point?

How many pairs of adjacent angles, in all, can you name in Fig. 8.36.

In Fig. 8.38, AOC is a line, find x.

In Fig. 8.39, POS is a line, find x.
