Answer 2

Step-by-step explanation:

(1)

$\cot(x) - \tan(x) = (2 { (\cos(x)) }^{2} - 1) \div \sin(x) \times \cos(x)$

$RHS = ( { \cos(x)} \div \sin(x)) - ( \sin(x) \div \cos(x) ) \\ = ({( \cos(x)) }^{2} - {( \sin(x)) }^{2}) \div ( \sin(x) \times \cos(x) ) \\ = ({( \cos(x)) }^{2} - (1 - {( \cos(x)) }^{2} ) \div ( \sin(x) \times \cos(x) )$

$= ( 2 {( \cos(x)) }^{2} - 1) \div ( \sin(x) \times \cos(x) ) = RHS$

(2)

$\tan(30°) =( height \: of \: tower) \div (distance \: of \: point \: away \: from \: tower \: from \: where \: angle \: of \: elevation \: is \: 30°)$

$(1 \div \sqrt{3} ) =( height) \div 30 \\ = > height = 30 \div \sqrt{3} = 10 \sqrt{3} m$
