Given: ΔABC; R midpoint of AB; F midpoint of AC; angle BAR=45°; angle RAF=15°
Angle BFC=?°
I solved it that way but instead of using the intercept theorem I used vectors.
I managed to solve it that way. Thank you for your help. However if you find another way to find that angle BMC is 120° I would like to hear it.
I told my teacher that I am searching for a solution in forum and he said that that's great. I showed him the phanthanhtom's reflections (thank you) and the teacher said that it's completely right and then he asked me to prove it. I couldn't do it because we haven't even used irrational numbers for lengths. He also said that the problem is easy to solve after you find the missing spot and let me to think over it two more days until our next lesson.
Thank you for your time. I am also still working on it.
P.S. The forum is incredibly usefull.
Thanks Bob.
But the problem is that I hadn't studied trigonometry yet.
