A. no; the domain values are at regular intervals and the range values have a common sum 1. b. no; the domain values are not at regular intervals. c. yes; the domain values are at regular intervals and the range values have a common factor 2. d. yes; the domain values are at regular intervals and the range values have a common sum 1.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

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)
