triangle abc has vertices a (0,7), b (7,3), and c (1,4): under the transformation rule, (x, y) —> (x-3,y-4), a’ would be (-3,3).
true
false

True

Step-by-step explanation:

Since the rule is (x, y) ---> (x - 3, y - 4), you would subtract 3 from 0 (the x value of A) which would be -3. Then subtract 4 from 7 (the y value of A), which would be 3. So the answer would be true, that A' would be (-3, 3).

(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
