Which statement can be concluded using the true statements shown?
If two angles in a triangle measure 90° and x degrees, then the third angle
In triangle ABC, angle A measures 90 degrees and angle B measures 50°.
A. Angle C must measure 50 degrees
B. Angle C must measure 40 degrees
C. Angle C must measure (90 - 40) degrees
D. Angle C must measure (90 - 30) degrees

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,
