Use the quadratic formula to find the solutions to the quadratic equation
below.
3x^2-5x+ 4 = 0

It will have complex and different roots.

Step-by-step explanation:

The solution is attached in the image below:

(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 answer is 99.
