    B. 67°

    Step-by-step explanation:

    An acute angle is an angle that has a degree that's less than 90°. This eliminates answers "C," and "D."

    The information above states that the triangle is right, meaning that one of its angles is 90°, and there's another angle that's 23°.

    So add these together, and subtract from 180 (all triangles are 180°), to get the other acute angle:

    90 + 23 = 113

    180 - 113 = 67°

    The missing acute angle is 67°
