My guess is C.
OpenStudy (solomonzelman):
you mean that
LM=11 and KM=45, right?
OpenStudy (anonymous):
No. Measurement of angle K is 45.
OpenStudy (anonymous):
yeah

you are given that:
~ \(\large\color{black}{ \angle K = 45^\circ }\)
~ \(\large\color{black}{ \angle M = 90^\circ }\)
~ \(\large\color{black}{ LM = 11 }\)

Right, and so we set up an equation. Sin45= what?
OpenStudy (solomonzelman):
but once you are given that angle K is 45 degrees, you can just use:
|dw:1420054938617:dw|
