Its 72, which is answer A

Answer 2

Answer: 72

Step-by-step explanation:

We know that the sum of all exterior angles of a polygon is 360°.

Therefore, by the given picture, we have

$(x+12)^{\circ}+57^{\circ}+108^{\circ}+60^{\circ}+51^{\circ}=360^{\circ}\\\\\Rightarrow x+288^{\circ}=360^{\circ}\\\\\Rightarrow\ x=360^{\circ}-288^{\circ}\\\\\Rightarrow\ x=72^{\circ}$

Hence, the value of $=72$
