Question

If these two shapes are similar, what is the measure of the missing length n?
39 in
15 in
91 in

Answer 1

Answer:

39in.

Step-by-step explanation:

due to scale, cant be 15, as that would be the same length as other side

cant be 91 otherwise it wouldnt be similar if it had the same length as blue triangle which has 39 not 15 as the top side
