The coordinates of point a on a grid are (2, -5). point a is reflected across the x-axis to obtain point b. the coordinates of point b are (2,

(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

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
