Master says that he can splits pizza to 16 parts by five equals straight cuts. Is it possible? - Obtuse angle

The line OH is the height of the triangle DOM, line MN is the bisector of angle DMO. obtuse angle between the lines MN and OH is four times larger than the angle DMN. What size is the angle DMO? (see attached image) - Circles

How many different circles are determined by 9 points at the plane if 6 of them lie in a straight line? - Trains

On a double-track line between stations, K and M went against each other two trains. The first train passed the distance between stations for 3.5 hours, the second, which had an average speed of 12 km/h more, passed for 3.05 hours. Calculate the distance - Lines
