Answer:
45, 45,90
30,60,3
Step-by-step explanation: A triangle must have 180 degrees to be a triangle. In the 45 45 90 it’s pretty straight forward that it is a triangle. In the 30,60,3 example it must be a right triangle due to 60+30 being 90 and the 3 allows for a right triangle. 3+4+5= a right triangle
