    Answer:

    -3.73

    Step-by-step explanation:

    solution:

    Given:

    Angle between two lines=60⁰

    slope of first line=1

    Or, tanA=1

    Or, A= tan inverse (1)

    so, A=45⁰

    so, angle of inclination of first line=45⁰

    Now,

    angle of inclination of second line= A+ 60⁰

    = 45⁰+60⁰

    =105⁰

    so, slope of second line = tan105.

    = -3.73
