Q8 of 107 Page 12

The tops of two poles of height of 20 m and 14 m are connected by a wire. If the wire makes an angle of 30° with horizontal, then the length of the wire is


Here ED = 14m and AC = 20 m are two poles


⇒ AB = 20 – 14 = 6 m


Wire AE connects them making angle with horizontal of 30°


We have to find AE which is length of wire


Sin 30° =


=


AE = 12 m
