Answer:

x = 15

The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.

Step-by-step explanation:

a. x 12

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

20 16

using cross products

x*16 = 20 * 12

16x = 240

divide by 16 on each side

16x/16 = 240/16

x = 15

b x 6

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

x * 8 = 6 * 20

8x = 120

divide each side by 8

8x/8 = 120/8

x = 15

c. The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.
