I must be doing something wrong still. I got f=36.44...

tkhunny · Answer

$\dfrac{71}{\sin(E)} = \dfrac{63}{\sin(36º)} \implies \sin(E) = 0.673108917947832$

Thus, $E = asin(0.673108917947832) = 42.3074684461896$º

Thus, $F = 180º - 36º - 42.3074684461896º = 101.69253155381º$

This is an example of how to SHOW your work.  This, "I got xxxxxx", just doesn't tell us much.  SHOW your work.

Based on that very large angle, when compared to the other two, the length of 'f' had better be greater than either of the other two.  Show the last step, please.

sin(42.31)/71=sin(101.69)/f
f * sin(42.31)=71sin(101.69)
f=71sin(101.69)/sin(42.31)
f=103.29
