This pair of figures is similar. Find the missing

Answer: x = 63
Step-by-step explanation:
since they are proportional to each other,
36/4 = 9
90/10 = 9
126/14 = 9
7*9 = 63
Answer:
x = 63
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{90}{10}[/tex] = [tex]\frac{x}{7}[/tex] ( cross- multiply )
10x = 630 ( divide both sides by 10 )
x = 63
