Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a test after 4 hours and I really need to know how to solve this :S

I tried my best and threw 4 pages of scratch papers already !!!

Please help me...

I know im doing it wrong, I tried and tried but it did not work .. Im really frustrated I feel like im going to fail the test -.-

The angles are not given so I have no idea how find these forces .. and the vertical force of 100Kn, how is it distributed to both sides ??!

This is all I can do until now :
