For each triangle sum of it's angles must add to 180°.
We need to check if these angles satisfy that condition:
32°+51°+97°=180°
They do satisfy. Now we check if any angle has value that is not possible.
32° and 51° angles are OK.
97° angle is also OK. It is obtuse angle.
For each angle measures exactly one triangle exists. In this example we have an obtuse-angle triangle.
If you have some thing like x^2 + x + x^3 + x^2 the correct order would be x^3 + x^2 + x^2 + x.

Answer:
5 hours.
Step-by-step explanation:
Note that the clock "restarts" at 12, and flips from PM to AM (and vice versa).
In this case:
1st hour: 10:36 - 11:36pm
2nd hour: 11:36pm - 12:36am
3rd hour: 12:36am - 1:36am
4th hour: 1:36am - 2:36am
5th hour: 2:36am - 3:36am
