Question

Solve using proportions.

Answer 1

Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

c           k

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

31.2 = 4k

Divide each side by 4

31.2/4 = 4k/4

7.8 = k
