7.1 Rays OA and OB form a right angle. Seventh-grader Petya drew rays OC and OD inside this angle, forming an angle of $10^{\circ}$, and then calculated all the acute angles between any pairs of the drawn rays (not only adjacent ones). It turned out that the sum of the largest and the smallest of the found angles is $85^{\circ}$. Find the measures of the three angles into which the right angle is divided by rays OC and OD.
