Hi Katlovesmath94

hahah hey :)

I'll let outkast explain since he is so eager

can you help me with this? I am not sure where to start and I am suppose to explain it

ok thanks

soooo I am still confused what am I doing?

yes

what am I putting in the pathagoreum therum formula

|dw:1343004042674:dw|

Looks like a good explanation going on here so far.

Do you got it? Or are you still confused on how to use the theorem to get the length of side BD?

like I tried the pathegorium thing and I got some rediculas numbers in the thousands

I am just frustrated with this problem

When you got the large numbers had you already taken the square root of the number?

no i just did the pathagorium thing squared them and then what i have two huge number equal to c^2

what are you plugging in for Pythagoras theorem?

the 35 and 12

alright that's good. You are doing the right thing.
\[12^2+35^2=c^2\]\[144+1225=c^2\]\[1369=c^2\]

now square root both sides....what do you get then?

37?

Good job! So c = 37 means the length of side BD in your picture is 37 feet.

We are done with triangle BCD. Now look at the next triangle, ABD.

tan60

yes

opposite is 35 but what is the adjacent? 37?

oh you multiply AD to both sides

OH my bad, I mean tan(60)=37/AD

you still multiply AD to both sides right

tan(60) = opposite/adjacent = 37 / AD

Yes.

You should get something in the 20s for your answer for AD if you calculate the tan(60).

Does it make sense?

21.361

Perfect. Good job :)

If you practice problems like this over and over they get easier.

Sorry about a couple of my typos there.
