What is f(-2)?
0 -3
0 -1
1
0 3

1

Step-by-step explanation:

The -2 is actually the X. I'm really good at this. So you look at the x part of the table, and see -2. You look to the right and there is 1! Hopefuly, this 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
