Question

The length of the hypotenuse in the figure is:

• A. 5
• B. 3
• C. 6
• D. 4

Answer 1

The correct option is A

5

Triangle ABC is a right angle triangle, right angled at B, so AC is the hypotenuse.
Therefore using distance formula,
$A{C}^2=(5-1{)}^2+(1-4{)}^2$
= 16 + 9
$A{C}^2=25$
$\therefore AC=5$
