    40°

    Step-by-step explanation:

    The sum of the 3 angles in a triangle = 180°

    Subtract the sum of the 2 given angles from 180 for third angle

    third angle = 180° - (90 + 50) ° = 180° - 140° = 40°

    Answer: B. 40

    Step-by-step explanation: A triangle's angles will always add up to 180 degrees. Add the 2 angles that are given. 90 + 50 = 140. Subtract this number from 180. 180 - 140 = 40. The third angle is 40 degrees.
