Answer:

13) x=12

14) x=63

15) x=77

16) x=5

Step-by-step explanation:

Because the triangles are similar, the ratios for the corresponding sides are the same. Set up ratios and solve for x in each, like I did in my page.

13) x = 12

40/10 = 4

3 * 4 =  12

14) x = 63

90/10 = 9

7 * 9 = 63

15) x = 77

84/12 = 7

11 * 7 = 77

16) x = 5

54/9 = 6

30/6 = 5
