The average of 1/5 and other two numbers out of which one is the half of the other is 1/4. the smallest fraction out of unknowns is:
a) 1/6 b) 11/60 c) 1 1/30 d) 1/2 e) 9/20

The smallest fraction is b 11/60

(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 correct answer is a.) bc< mn 5 stars if this you : )
