Question

In the figure two straight line AB and CD intersect at O. if angle COD=60. Find a,b and c......plz answee guys...​

Answer 1

Step-by-step explanation:

4b=a

b=a/4

---------------------

2c=60+b

the sum of angles=360

4b+2c+a+b+60=360

4b+60+b+4b+b+60=360

10b=360-100

10b=260

b=260/10

b=26

a=4*26=104

2c=60+26=86
