    Answer:

    a) (5, 2, 2)

    Step-by-step explanation:

    According to length property of a triangle, sum of two sides of a triangle is greater than the third side.

    a) 2 + 2 = 4

    4 < 5 (not a triangle)

    b) 3 + 4 = 7

    7 > 5 (it is a triangle)

    c) 5 + 12 = 17

    17 > 13(it is  a triangle)

    d) 4 + 7 = 11

    11 > 8 (it is a triangle)

    Answer:

    (a) (5,2,2)

    Sol: We know that ,

    The sum of the lengths of any two sides of a triangle is

    greater than third side.Here, 5cm+2cm =7 cm > 2cm

    2cm + 2cm = 4cm < 5cm

    So ,

    The triangle with sides 5cm ,2cm and 2cm is not

    possible.

    (b) (3,4,5)

    Sol: We know that ,

    The sum of the lengths of any two sides of a triangle is

    greater than third side.

    Here, 3cm+4cm =7 cm > 5cm

    4cm + 5cm = 9cm > 3cm

    5cm + 3cm = 8cm >4cm

    So ,

    The triangle with sides 3cm ,4cm and 5cm is possible.
