Answer 1

28

Explanation:

First we can use something called opposite angles. This means that the angle opposite Q is also 140. 140+140=280

Angles in a circle adds up to 360. 360-280=80 this is the total of both angles so we divide by to to make 40.

We can then make an equation with this.

40=x+12

28=x
