Answer 2

Answer: 72

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`
