10 points! here are the options.

a. a(1, -1), b(-1, -2), c(0, -1)

b. a(-1, 1), b(1, 2), c(0, 1)

c. a(-1, -1), b(-2, -1), c(-1, 0)

d. a(1, 1), b(2, -1), c(1, 0)

e. a(1, 2), b(-1, 1), c(0, 1)

The Correct answer is choice B) (-1,1) (1,2) (0,1)

Step-by-step explanation:

reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

B) (-1,1) (1,2) (0,1)

Step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

$12. that is my answer.
