Question

in the given figure if BOC 7x+20 COA 3x AOB is a straight line then x​

Answer 1

Answer:

X= 16

Step-by-step explanation:

Given that angle BOC is 7x+20 and angle COA = 3X And AOB is a straight line so we can apply linear pair property

So,

(7x+20)+ 3x=180 ( linear pair property)

10x+20 = 180 (sending +20 to right hand side it becomes - 20)

10x=180-20

10x=160

X= 16
