+208 Hey there!
First you must find what the angles are. Angles \(KJL\) and \(MLN\) are equal, we can use this to find \(x\),
\(6x-2=5x+10\)
\(x=12^o\)
Using this you now know what all angles are going to be:
\(KLJ=70^o,MLN=70^o, NML=65^o, KJL=60\)
Also using the knowledge that there is \(180^o\) in a triangle you can find the last 2 angles:
\(JKL=180-70-60=50^o\)
\(MNL=180-70-65=45^o\)
Finally you can use this to find the true statements that you have provided.
Let me know how you go :)
