Answer 2

Explanation:

From the given figure , we can see that there are two angles whose measures are x and 2x - 30°. If we notice they are the angles on the same segment . ( Draw a line through the end points of the two lines , and they will be on the same chord) . And we know that angles of the same segment are equal . Therefore ,

`\tt\to x = 2x - 30^o \\\\\tt\to 2x - x = 30^o \\\\\tt\to\boxed{\orange{\tt x = 30^o }}`

This is our required answer.
