# 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 isA. 12 mB. 10 mC. 8 mD. 6 m

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
