Answer 1

A)\[\sqrt{89}\]
B) \[\sqrt{39}\]

Answer 2

Ok so this forms a shape that can be divided into two to form two right triangles.

Answer 3

So since we have the coordinates, you can use the distance formula to find the distance between the points.

Answer 4

Distance formula is \[\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\]

Answer 5

Can you go on from there?

Answer 6

yes thank you :)
