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

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
