Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.
1) we calculate the number of minutes from 6:10 to 7:00 
number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.
2)
We know that:
60 minutes of a clock have turned -360º 
Then:
60 minutes of a clock------------------------- -360º
50 minutes of a clock-------------------------      x
x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º
Answer:  A. -300º

Hey there! I"m happy to help!
The interior angles of a triangle add up to 180. We have 2 angles that have a value of x, so 2x+138=180.
We subtract 138 from both sides.
2x=42
We divide both sides by 2 
x=21.
Have a wonderful day! :D
