When would you use a drawing of comparison bars for a word problem?

when trying to compare 2 different things by giving a visual example, for example when discussing the number of games 2 teams have won throughout the season.

phosphate, calcium ion, chloride ion, neon atom

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
