Question states- Find x to make each of the figures proportional to each other.

Answer 1

x = 5

Explanation:

for the figures to be proportional then the ratio of corresponding sides must be in proportion, that is

`(x)/(20)` =
`(3)/(12)` ( cross- multiply )

12x = 20 × 3 = 60 ( divide both sides by 12 )

x = 5
