From the top of a mobile tower \(h \ m\) high, the angles of depression of two objects, which are in line with the foot of the tower are \(\alpha\) and \(\beta\) (\(\beta > \alpha\)). Find the distance between the two objects.
 
Answer:
 
\(tan\ \beta = \)
 
\(y=\)
 
\(tan\ \alpha=\)
 
\(x = \)
Answer variants:
\(h(tan\ \alpha - tan\ \beta)\)
\(h(cot\ \alpha - cot\ \beta)\)
\(h(cot\ \beta-cot\ \alpha)\)
\(\frac{y}{h}\)
\(\frac{h}{x+y}\)
\(\frac{h}{y}\)
\(\frac{h}{tan\ \beta}\)
