Answer:
For trapezoids, we have some rules:
The angles always need to ad up to 360°
We also have that the base angles are suplementary, so they need to ad to 180°. (one smaller or equal than 90° and the other greater or equal than 90°)
Then, if the angles are one equal to 60° and the other 45°.
The other two angles are:
a1 = 180° - 60° = 120°
a2 = 180° - 45° = 135°
and now we have: 120° + 60° + 45° + 135° = 360°
for the other we have an angle of 60° and other of 120°.
This two angles can be one next to the other, so may be suplementary.
this mens that the other two angles may be any angles that add to 180° (again, one is less or equal than 90° and the other is greater or equal than 90°)
So we can have:
a1 = 110°
a2 = 70°
for example.
