Question

find the value of a.​

Answer 1

Step-by-step explanation:

2a+3a+a=360

6a=360

a=360/6

a=60

3a=60x3=180

2a=60x2=120

a=60

so, 180+120+60=360

Answer 2

Answer:

Hello....

From figure,

We can see that angle (DOF) is equal to angle (EOC) as they are vertically opposite angles...

So the value of angle (EOC)=3a

So by using linear pair test,

2a+3a+a=180°

6a=180°

So...

a=30°...

Hope this helps...❤❤☺☺
