what do you mean by "that is the length of the altitude to side AD" in the first place?

i don't know what that exactly means... or else i wouldn't have asked this question :\

dont you mean like how high above ground level is the parallelogram?

or something like that?

maybe ( or are you referencing the height)?

altitude is a reference to how high above or how low below ground/sea level

great, i just figured it out and i hate it

are you in trig rn?

@calculusxy
i think i figured it out if you werent paying attention

no i don't know trig very well, but i can work with sine, cosine, tangent (only the basics)

thats what this is

line BC is going to be ground level for this

i don't quite understand what you mean

@surjithayer Can you plz explain this to me more?

thx show off

basically multiply the sine of 60 degrees by 12 to get your answer

h is altitude
|dw:1442980656562:dw|

\[\sin 60=\frac{ \sqrt{3} }{ 2 }\]

i just said everything he put up there in a nice sentence without any complication

and how do i evaluate that @surjithayer

\[h=12 \sin 60=12*\frac{ \sqrt{3} }{ 2 }=6\sqrt{3}\]

oh okay ! but is there any simper way of doing it?

and the perfect example is the one above

That's about the easiest way to do it with the given information.

i seriously think that letting someone finish there answer and explanation should be on the CoC
