Answer 2

Answer:

$\frac{15}{2} ( \sqrt{3} - 1 ) = 7.5( \sqrt{3} - 1) \: \: metres.$

Step-by-step explanation:

$\frac{h}{15 - h} = \tan(60) \\ \\ \frac{h}{15 - h} = \sqrt{3} \\ \\ h = 15 - \sqrt{3} h \\ \\ h(1 + \sqrt{3} ) = 15 \\ \\ h = \frac{15}{1 + \sqrt{3} } = \frac{15}{2} ( \sqrt{3} - 1 ) = 7.5( \sqrt{3} - 1) \: \: metres.$
