    Angles add up to 180

    if right triangle, one angle is 90

    another is 15 as given therefor

    180=15+90+x

    180=105+x

    subtract 105

    75=x

    angle is 75 degrees

    because all triangles angles add up to equal 180, and a right triangle has a 90 degree angle. you subtract 90 and 15 from 180 and that number will be the size of the remaining angle

    180-90=90

    90-15 = 75

    the answer is B) 75degrees
