11. order the set of numbers from least to greatest
-15, 9.6, -2.4, 0.5, -6.3

-15, -6.3, -2.4, 0.5, 9.6

Step-by-step explanation:

The higher the number is when you add a negative sign, the lower the number

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

(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
