Question

The remedy is experience.. And I don't have any..
Help please ?

Answer 1

First find the length of BD using △BCD

Answer 2

using Pythagorean theorem

Answer 3

\[BD^2=18^2+24^2\]\[\therefore BD=\sqrt{18^2+24^2}\]
(you can remove the common factor of 18 and 24 out to make the math easier)\[\implies BD = 6\sqrt{3^2+4^2}=6\sqrt{25}=\Large 30 ft.\]

Answer 4

Thanks :)

Answer 5

Then to find AD you need to know trigonometry ....OR at-least the ratios of the sides of 30-60-90 triangles.

Answer 6

Do what ?

Answer 7

In 30-60-90 triangles the ratios of the sides is always \[\Large 1:\sqrt3:2\]
