I have just learned the origin of this hard easy exercise https://en.wikipedia.org/wiki/Langley%E2%80%99s_Adventitious_Angles

LCKurtz, you are right <OBA=50°, we can obtain that value by checking the angles in the triangle ADB

Hi, I think I finally understood the solution for this exercise. I've uploaded an additional image with the solution https://goo.gl/photos/CAacV2dJbUrywfXv9 First find out <OBA=50°, since OB bisects <ABT2, <OBD=10°. The trickiest part of this exercise was finding out that the quadrilateral...

Yes, it is an exercise from a book, the center is at the beginning of the dashed line. Can I safely say this exercise has missing information?

Thanks for the reply, the only given data is what is shown in the picture. Yes T1T2 doesn't go through the center, but the segment that comes from A do. The additional information I mentioned comes from my attempted solution (CAD software) but I'm not sure

Homework Statement In the drawing you can see a circumference inscribed in the triangle ABC (See the picture in the following link). Calculate the value of X https://goo.gl/photos/CAacV2dJbUrywfXv92. The attempt at a solution It seems I found a solution for this exercise with the help of a...
