At this point, the plane started descending. As the plane turned, it's altitude dropped from 3060 feet to 1650 feet above the ground level. Calculate the angle of descent (in degrees) if the plane traveled 0.5 miles.

1 1/5

step-by-step explanation:

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)

i don't think there is enough
