Note: angle BDC is 60 degrees and ABE is 30 degrees ABCD is a rectangle. AB = 1, and BE and BD intersect ABC. What is the perimeter of BDE?
choices:
A. about 5.4371
B. about 5.0432
C. about 4.8869
D. about 4.3094​

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)
