Question

The top of two pillars whose heights are 20m and 14m are joined by a wire. If the wire makes an angle of 30 with the horizontal line,then the length of the wire is

Answer 1

Find the difference in the height:

20 - 14 = 6m

Find the length of the wire:

Sin θ = opp/hyp

sin (30) = 6/length

0.5 = 6/length

length = 6 ÷ 0.5

length = 12 m

Answer: The length of the wire is 12m

Answer 2

Hey mate here is your answer

Distance between two poles

30-24=6m

Tan 30°= 6/x
$\frac{1}{ \sqrt{3} } = \frac{6}{x}$
$= 6 \sqrt{3}$
Right angle triangle ⛛

${(6 \sqrt{3)} }^{2} + {6}^{2} = {y}^{2}$
36*3+36=y^2
y^2=144
Y=12

Lenght of the wire is 12m

Hope it will help you
