Question

What is the length of segment AB

A) 3
B)
`√(20)`
C)
`√(41)`
D) 9

Answer 1

Answer:
`\large \boldsymbol {C) \ AB=√(41) }`

Explanation:

• The formula for the distance between points:

• 
  `\bf AB= √((x_2-x_1)^2+(y_2-y_1)^2)`
• Coordinates of point A (0;5 ); coordinates of point B(4;0)
• 
  `\bf AB= √((0-4)^2+(5-0)^2) =√(16+25) =√(41)`
