Answer» Answer: Given that : Heights of two POLES are 20 and 14m respectively. Angle wire makes with horizontal =30 ∘
Let distance between two poles be x and LENGTH of wire be y tan30 ∘ = x 20−14
= x 6
1
= x 6
⇒x=6 3
As length of the wire will form the hypotenuse of right ANGLED triangle thus formed, y 2 =6 2 +(6 3
) 2 =144 ∴y=12 m |
