Best ResponseYou've already chosen the best response.0Congruent means equal, so when they say QR is congruent to LN, they mean QR is equal to LN.

Best ResponseYou've already chosen the best response.0Since they want us to find x as well as y, and they give us two cases(LN=QR; OP=VW), it means we will probably have to use a system of equations.

Best ResponseYou've already chosen the best response.0Elimination does not work with these equations. If it did you would be left with either just the xvariable in your answer or the yvariable in your answer, but not both at the same time.

Best ResponseYou've already chosen the best response.0We have to use substitution. What we are going to do is pick one of the two original equations and completely isolate a variable. (either x or y will work).

Best ResponseYou've already chosen the best response.0but would that be the answer? because it looks weird, and when I solved it (or attempted to) it was a decimal.

Best ResponseYou've already chosen the best response.0No. it is not. Okay, now we have to get the other equation and substitute y into it. Like so. dw:1439265853745:dw

Best ResponseYou've already chosen the best response.0We now have a onevariable equation.
