The top of two poles of height 24 m and 36 m are connected

Home » Aptitude » Trigonometry » Question

The top of two poles of height 24 m and 36 m are connected by a wire. If the wire makes an angle of 60° with the horizontal, then the length of the wire is

DE = 36 – 24 = 12 metre
From ∆ ADE,

sin 60° =	DE
	AD

⇒	√3	=	12
	2		AD

⇒ AD =	12 × 2	= 8√3 metre
	√3
