Step-by-step explanation:
Similar figures have same ratio of corresponding sides.
Set up ratios and solve for x.
#1
- x / 54 = 6 / 36
- x / 54 = 1/6
- x = 54/6
- x = 9
#2
- x / 4 = 99 / 11
- x / 4 = 9
- x = 4*9
- x = 36
#3
- x / 10 = 6 / 60
- x / 10 = 1/6
- x = 10/6
- x = 5/3
#4
- x / 4 = 28 / 7
- x / 4 = 4
- x = 4*4
- x = 16
