The vertices of figure PQR are P(0, 1), Q(2, 3), and R(4, 1). What is the
correct coordinate of Q after a reflection
across the line x = -1.
A (-5, 1)
C. (-2, 1)
B. (4, -3)
D. (-4,3)

Its B

Step-by-step explanation: I wrong But next time licence to you teacher when she go's over it and dont shake you camera

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
