Solve for x: the quantity of x plus 20 over 2 = 3x

x = 5

Step-by-step explanation:

(5) + 20/2 = 3(5)

Hope it helps

(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

the first one, all those points on the line just make a strait line.
