Drag the tiles to the boxes to form correct pairs. Helen has come to a party with four of her friends. Each one of them interacts differently with others. Helen quietly observes and tries to understand the gestures of her friends. Help Helen by matching the gestures to the likely meaning they show.

- Acceptance and openness - Smile

- Restricted and distant - Crossed Arms

- Disapproval over something - Frown

Explanation:

Gestures are described as 'a motion of the body or limbs to express or communicate a specific message, attitude, idea, etc.' The given gestures have correctly been matched with the meaning or ideas they are conveying. 'Smile' reflects one's attitude of compliance and openheartedness towards fellow beings. While 'crossed arms' express that the person is confined in himself and likes to stay distant from others. 'Handshake' shows the common view and signals that the person is proposing an interaction. And 'Frown' denotes one's disagreement and objection over a specific point or topic.

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.

give some choices then i can answer
