PLEASE HELP What is the distance between points Rand S, to the nearest tenth of a unit? A. 6.3
B. 7.2
C. 14.4
D.20.0

C. 14.4

Step-by-step explanation:

We need to find the distance between the points vertically, horizontally, and finally diagonally. These distances will ultimately form a right triangle meaning we will solve the distance between the points with the Pythagorean Theorem.

X-axis distance = 4 - (-8) = 12

Y-axis distance = 2 - (-6) = 8

Now we use the Pythagorean Theorem and substitute the calculated values for a and b.

a² + b² = c²

12² + 8² = c²

144 + 64 = c²

208 = c²

14.4 = c

42.4

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
