There is many answers to this question but angle B and C have to add up to 140 so angle B and C could both be 70 that should work

Answer:

The other possible angles would be 90º (Right tringles always have a 90º angle) and 50º

Step-by-step explanation:

To find the 3rd angle (the 50º one) all tringles angles add up to 180º. Since you already have 40º and 90º

you would subtract those from 180.

180º - 40º - 90º = 50º
