Luca needs to solve the equation x2−2x+2=0 by completing the square. which pair of steps is the most efficient way to begin?

^2−2=−2

^2−2+1=−2+1

(top right)

just needed some points but try socratic

(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
