  2. 12/16 = x/20
    3/4 = x/20
    15/20 = x/20
    x = 15

  3. Answer:

    Part a) x=15cm

    Part b) x=15cm

    Part c) The answers are the same because the triangles are similar, therefore the ratio of their corresponding sides are equal

    Step-by-step explanation:
    we know that
    If two triangles are similar, then the ratio of their corresponding sides are equal and is called the scale factor

    Part a) Find x using the ratio of the sides 12 cm and 16 cm
    so
    12/16 = x/20
    3/4 = x/20
    The ratio of their corresponding sides is called the scale factor and in this problem is equal to 3/4.
    solve for x
    x = 20 * 3/4
    x = 15 cm

    Part b) Find x using the ratio of the sides 6 cm and 8 cm
    so
    6/8 = x/20
    3/4 = x/20

    Observe that the scale factor is equal to 3/4
    solve for x
    x = 20 * 3/4
    x = 15 cm
    Part c) The answers are the same because the triangles are similar, therefore the ratio of their corresponding sides are equal
