Answer:
The given angle is negative
Adding or removing 360 degrees from an angle has no effect on its position.
Therefore, Angle can also be written as=-40° + 360° = 320

• Draw a straight line from point A to point B.
• Make a mark at B. The vertex of the angle is represented by this dot.
• Place the protractor’s centre at B and the protractor’s baseline along the arm BA.
• Locate 320° on the scale and make a little dot on the protractor’s edge.
• Using a ruler, join the vertex B to the little dot to make the angle’s second arm, BC.
• Draw a little arc to indicate the angle, as illustrated below.
