Hmm...lol, the drawing is a bit unclear..

Lol, I know it's kind of hard to read.

I dont know where the 2 goes, lol.

There was no 2 and it was 5.2

Thers a more clearer version.. As you can see, this looks like an isosceles.

28TylerrBest ResponseYou've already chosen the best response.0
Ahh, Yes it kinda looks like a triangle split in two

Now..because of this one rule..lol, sorry forgot the rule, but remember its function, but it stated that that line in the middle, i think altitude its called, not sure, that separates the triangle, makes the two halves equal.

So, basically, that means: dw:1337041876443:dw

Ok, Would I use the a2 + b2 = c2 and the a=1/2bh?
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Yes..I have found all the necessary lengths, all you need to do is plug it in to your formula.
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
So.. What is our base?
 one year ago

28TylerrBest ResponseYou've already chosen the best response.0
Ok, Would it be like this: 7^2 + 7^2 = 5.2^2?
 one year ago

28TylerrBest ResponseYou've already chosen the best response.0
Or would you add the 2 5.2's to make 10.4?
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Use Pythagorean Theorem. Our hypotenuse, or "c" is 7 our leg 1 or "a" is 5.2 we need to find leg2 or "h"

28TylerrBest ResponseYou've already chosen the best response.0
Ok, So how would I set that up?
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
\[a ^{2}+b ^{2}=c ^{2}\] \[(5.2)^{2}+b ^{2}=7^{2}\] \[27.04+b ^{2}=49\] \[27.04Subtract \] \[b ^{2}=4927.04\] \[b ^{2}=21.96\] \[b=4.7\]

Our "b" will substitute as our "h" or height.

GOODMANBest ResponseYou've already chosen the best response.1
So, now we have all the components of our triangle. A=1/2bh A=1/2(10.4)(4.7) A=1/2(48.88) A=24.44

28TylerrBest ResponseYou've already chosen the best response.0
Would that be my answer and my answer for my area
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Yes..that would be your area.

28TylerrBest ResponseYou've already chosen the best response.0
Mhmmk, can you help me with 1 more like this?
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Okay..but I gotta hurry. I have some trig functions, lol.

 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Like that? Is it isosceles as well?
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Okay, because of the altitude, we can also determine this..dw:1337042961699:dw
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Now.. We have our formula. A=1/2bh Our Base: 16 And our height: 5

28TylerrBest ResponseYou've already chosen the best response.0
Can you show me some work for that plz on both? (:

GOODMANBest ResponseYou've already chosen the best response.1
A=1/2bh A=1/2(16)(5) A=1/2(80) A=40

28TylerrBest ResponseYou've already chosen the best response.0
What about for a2 + b2 = c2
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
We didn't need the Pythagorean Theorem, because we had all the necessary lengths to find the Area.
 one year ago

28TylerrBest ResponseYou've already chosen the best response.0
Oh ok so all I needed was the Area because
 one year ago

28TylerrBest ResponseYou've already chosen the best response.0
I had all of the lengths
 one year ago

GOODMANBest ResponseYou've already chosen the best response.1
Yes..but the first one, we needed the height, and we used the Pythagorean Theorem to find it. In this problem, we already had everything we needed to find the Area.

Ok, I thank you for all of the help Goodman. Hopefully you can help me some more some other time. Thank You (:
