Answer 2

Answer:

x= 16°

Step-by-step explanation:

${\huge{\bf{\underline{\green{Solution :}}}}} </p><p>$

Since Angle AOB is a straight line, Angle BOC and Angle COA forms a linear pair.

Therefore,

Angle BOC+ Angle COA= 180°

7x+20+3x= 180

10x+20= 180

10x= 180-20

10x= 160

x= 160/10

x= 16/1

x= 16

Therefore, The value of x is 16°.
