The graph below shows the number of chairs arranged with different numbers of tables in a room a) there are 4 chairs for every 1 table in the room. b) there are 4 tables for every 1 chair in the room. c) the ratio of chairs to tables in the room is 5: 1 d) the ratio of tables to chairs in the room 5: 1

WHAT THEY SAID ON TOP OF ME.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

(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
