Answer:
If it's choose all that apply then it's right and complementary.
Step-by-step explanation:
The little square in the corner tells you that angle is a right angle.
A complementary angle is, two angle measurements that add up to 90°. In this case since the whole figure is a right angle, a.k.a 90°, that's why the smaller angles would be complementary.
I hope this makes sense, and is correct :)
