Which choices are correctly written in scientific notation? check all that apply. •a. 17.1x10^3 •b. 8.05x10^3 •c. 6.25x4^3 •d. 4x10^-16 •e. 22.09x10^-9 •f. 3.03x10^-1 •g. 5x10^10 •h. 3.44x1^10

B. 8.05x10^3

D. 4x10^-16

F. 3.03x10^-1

G. 5x10^10

(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

24+x=y
