Question

PLEASE ANSWER ASAP IF YOU KNOW THIS..... To the nearest hundredth, what is the length of line segment AB ?

Drag your answer into the box.
The length of line segment AB is approximately ______ units.

choices: 2.83, 1.41, 4.00, 5.83, AND 7.21

Answer 1

The answer will be 5.83 because if you drag your mouse or your finger over the line you will count that the line crosses over 5 and a little bit units.

Answer 2

Imagine a right triangle being made from this line, with segment AB as the hypotenuse. The missing point of the triangle would be on (-4,-5) Lets name the point C

Okay, so since we have a right triangle, we can solve for the length of AB using the pythagorean theorem.

a²+b²=c² where a and b are side lengths and c is the hypotenuse

The distance from A to C is 5units
The distance from B to C is 3 units

Plug in the data that we know

5²+3²=c²
25+9=c²
34=c²
√34=c
5.830=c
round to the nearest hundredth
5.83=c

Answer=5.83 units
