Helps pleaseee I've been stuck for forever (brainliest) Parallelogram JKLM is shown on the coordinate plane below:

If parallelogram JKLM is rotated 270° counterclockwise around the origin, what are the coordinates of the endpoints of the side congruent to side KL in the image parallelogram?

K′(−4, −6); L′(3, −3)
K′(6, 4); L′(3, 3)
K′(−6, −4); L′(−3, −3)
K′(−4, 6); L′(−3, −3)

K′(−6, −4); L′(−3, −3)

Step-by-step explanation:

Use (x,y) -> (y,-x).  Find the KL points and and just use that method.  

Also, you can rotate the image 270 degrees and count.  

(Please note I may be wrong and please correct me if I am.)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

126 maybe. sorry
