    Step-by-step explanation:Let a be the length of line

    from question we know that

    a+3 is another line

    Here

    a + (a+3) = 15. (Given in question)

    2a = 15 - 3

    2a=12

    a=12/2

    a=6

    Here a and a + 3 are the length of the line

    Finally, 6 and 9 are the lengths
