Triangle OPQ is similar to triangle RST. Find the measure of side RS. Round your answer to the nearest tenth if necessary. OPQR need this answered quick ​

RS  =  75.3

Step-by-step explanation:

You need to set up the proportion of corresponding sides.

7(RS) = 31(17)

         =  527

RS = 527/7 = 75.2857...

     =  75.3

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
