3. what is the equation of the xz-trace for the plane 7x 2y + 3z = 19?

7x + 3z = 19

7x 3z = 19

2y + 3z = 19

2y + 3z = 19

(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

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo
