33. Given the proportion a/b=c/d solve for c

Step-by-step explanation:

Given proportion:

                        =  

To solve this problem, make c the subject of the expression.

  Cross multiply;

                 ad  = cb

Now, divide both sides by b,

        =  

          b  =  

step-by-step explanation:

where is the questions

(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
