Angle ABC is taken by a dilation with center P and scale factor 3 to angle A’B’C’. The measure of angle ABC is 21 degrees. What is the measure of angle A’B’C’? Explain how you know

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
