Answer:
B
Step-by-step explanation:
I dont get the first statemet, that 2 angles are 90 degrees, because that isnpt possible for a triangle, but a triangle must add up to 180 degrees, and if you have one that is 90 degrees, then you are half way there, then you get 50 more degrees, and you have 40 left, so B is the answer angle C is 40 degrees,
