Answer:
10
Step-by-step explanation:
x/20= 5/x
x²= 100
x=√100
X=±10
x=10
Answer:
x = 10
Step-by-step explanation:
expressing the ratios in fractional form
[tex]\frac{x}{20}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )
x² = 100 ( take square root of both sides )
x = ± [tex]\sqrt{100}[/tex] = ± 10
the positive solution is x = 10
