    正确答案： C
    解析：
    If the angles of a triangle are in the ratio of 3: 4: 5, let 3x, 4x, and 5x represent the measures of the three angles. Since the sum of the measures of the angles of a triangle is 180, 3x+4x+5x = 180, 12x = 180, x=180/12 = 15. Hence, the measure of the smallest angle of the triangle is 3x =45.
