Question

question 9 of 10 the two prisms below are similar. what is the value of x? a. 5 b. 10 c. 1 d. 15

Explanation:

Step1: Find the scale - factor

The ratio of corresponding lengths of similar prisms is the same. Compare the lengths of the known corresponding sides. The ratio of the lengths of the two prisms for the side with lengths 3 and 15 is $\frac{15}{3}=5$.

Step2: Calculate the value of x

Since the scale - factor is 5 and the corresponding side to x has length 1, then $x = 1\times5$.

Answer:

A. 5
