A line has endpoint at (2, 1) and (8,9). What is the distance between the points? 200
100
10
2

Distance between points (2, 1) and (8,9) is 10.

Step-by-step explanation:

let me know if you need an explanation :)

hope this helps and is right. p.s i really need brainliest :)

10

Step-by-step explanation:

distance formula is the square root of x sub 1 - x sub 2 quantity squared +y sub 1 + y sub 2 quantity squared. In this case it would look like the square root of (8-2)^2 +(9-1)^2. this would simplify to the square root of 100, which is 10.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

-81 -56 -27 0 81
