Triangle to find BCD

survival · 2011-05-02 12:17:23

Could someone please work this. It is driving me nuts.

The numbers to this fuzzy picture are (72-11x) degrees +(41-6x)degrees = (92 - 24x) degrees
The equation reads:
For the given triangle, find the measure of the exterior angle BCD.
The measure of angle BCD is________
A total of three answers, different lines.
Thank you.

Hi survival;

I can not read that at all. Do you know how to use an online whiteboard?

survival · 2011-05-02 15:00:25

hey, no, I don't know what that is. Tell me.

bobbym · 2011-05-02 15:02:13

Please go here and play with it for a while. You might be able to draw your figure and save it. Then I will tell you how to upload it.

Ok, i will do that. Didn't tell you i was an real artist did i? LOL

bobbym · 2011-05-02 15:26:50

Are you drawing what you want?

survival · 2011-05-02 15:36:24

it keeps turning into another type of triangle.
Tell ya what. Just solve the equation and i will figure out the last three parts. How's that?

(72 + 11x) + (41 + 6x) = (92 - 24x)

bobbym · 2011-05-02 15:43:02

That is not likely as the answer for x is - 21 / 41.

survival · 2011-05-02 15:48:34

oh me, that is a fraction. Won't work. I have messed with this problem for days on and off. Kept clicking over to a new one, and the last part is the hold up. I am sure it's simple. I want to take geometry someday. I like this stuff.

survival · 2011-05-02 15:49:37

oh and the due date is tomorrow night i think. LOL

bobbym · 2011-05-02 15:50:38

Go back to the dabbleboard and click freehand. That will turn off the shape recognizer. Then you will be able to draw what you like.

survival · 2011-05-02 15:59:38

ok, will see how it goes. thank you.

survival · 2011-05-02 16:38:53

what do you online besides math?

bobbym · 2011-05-02 16:41:26

I am currently on 4 or 5 math forums. So that keeps me busy.

How is the drawing coming along. Have you figured the palette yet?

survival · 2011-05-02 16:54:08

Five is a lot. wow. I have never been on any of the others. I would worry them I suppose. LOL

I have one day to find out how to finance a down payment by savings accrued monthly over ten yrs. at 6 %. It is the last part of my three projects. I got perfect score on the second part, first part just so so.
There are 3 fantasy houses. Well two fantasy houses and one that a person would settle for.

Yes, I know about that question. One thing at a time. What about the drawing? Were you able to get it finished?

survival · 2011-05-02 17:49:25

sorry, i didn't get to finish it. This is my last week and i have finals, etc.

bobbym · 2011-05-02 20:22:17

gAr has answered your finance question. He is a good man with accurate results.

I am sorry you did not finish the picture. Next time you are in here I will try show you how. Tell me how you do on your exams.

hi survival,

Just picked this up after being away for a while.

So can you now work out the angles in the triangle. I cannot make out from your original diagram.

The exterior angle of any triangle is the sum of the two opposite angles in the triangle ( by use of angle sum = 180).

If that's not enough describe it in words like this:

In the triangle ABC the angle BAC = ..... etc.

LATER EDIT

Aarrggh. I think I've got it. The diagram has two internal angles (72-11x) and (41-6x) and the exterior angle opposite these and equal to 92 - 24x.

So I guess the exterior angle you are seeking is 92 - 24x where x = -3 .... = 92 + 72 = 164.

EVEN LATER EDIT

Is this the diagram below?

Bob

Yes, that's the one except the line is turned to the right. I did finally get the right answer after I flipped the problem and it gave me a new one. I still don't understand it but it is correct now.
Yours solution was correct too.

Thanks, I will let you know. I have tomorrow and a test on stats/other class test yesterday was a tough one. Too many numbers upstairs to think straight.

Hi survaival;

Just relax and everything will be fine. The great Bo Burton used to say."Trust is a must or your game is a bust."

hi survival

Yes, that's the one except the line is turned to the right.

I think your picture may be 'back to front' on the post. D and C look that way to me.

Anyway, not to worry, we got there!

Good luck with the tests.

Bob

Hello, Well, not many tests left. This is it nearly. LOL
