Question

If these two shapes are similar, what is the measure of the missing length? (picture is shown)

Answer 1

Answer:

Both a and b

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides is equal

In this case, the name of the triangle is not given, so any side can correspond to any side. but we have 2 non specified lengths(no variable or value assigned) and 1 specified but unknown value p

so we can have 2 cases:

1) p/9 = 24/21 -> p = 216/21 = 72/7 = 10.285714

2) p/21 = 24/9 -> p = (21×24)/9 = 7×8 = 56

so both a and b can be the answer on proper subjective norms.
