Question

15. In Figure 5, ZAOB and ZCOB form a linear pair. Find the measure of x.​

Answer 1

Step-by-step explanation:

Here by using linear pair,we get

AOB+BOC=180

x/2+x/3=180

3x+2x/6=180

5x/6=180

5x=180*6

x=180*6/5

x=36*6

x=216

So.angle AOB=x/2 =216/2=108 degree

and angle COB =x/3=216/3=72 degree
