  1. Answer:
    The 2 angles are 10 and 45 degrees.
    Step-by-step explanation:
    Angles in a triangle add up to 180 degrees.
    180 – 125 = 55
    Add the ratios 2+9 = 11
    Divide the left over angels by the ratio: 55/11 = 5
    Now multiply 5 by each side of the ratio:
    2:9
    2*5 = 10
    9*5 = 45
    So the 2 angles are 10 and 45 degrees.
    To check, add up all the angels : 10 + 45 + 125 = 180
