Question

This pair of figures is similar. Find the missing

Answer 1

Answer: x = 63

Explanation:

since they are proportional to each other,

36/4 = 9

90/10 = 9

126/14 = 9

7*9 = 63

Answer 2

x = 63

Explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

`(90)/(10)` =
`(x)/(7)` ( cross- multiply )

10x = 630 ( divide both sides by 10 )

x = 63
