Geometry Help. Question in the comments :) In triangle KLM, LM=11 and angle K=45. Find KL. Leave your answer in simplest radical form. A. 11 B. 22 C. 22*sqrt2 D. 11*sqrt2
My guess is C.
you mean that LM=11 and KM=45, right?
No. Measurement of angle K is 45.
yeah
\(\large\color{black}{ \angle K=45^\circ }\)
\(\large\color{black}{ \frac{\LARGE \sin(K^\circ)}{\LARGE LM} =\frac{\LARGE \sin(M^\circ)}{\LARGE KL} }\)
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?
but once you are given that angle K is 45 degrees, you can just use: |dw:1420054938617:dw|
