Hello all,
I joined because I have a quick question on some basic geometry/higher algebra 1. (and since you all seem to be college students, maybe you could help me out?)
Here's my problem:
The measures of two supplementary angles are 4r - 7 and r - 2. Find the measure of the angles.
Now, from looking back at my notes, supplementary angles are angles that equal to 180 degrees. So... all that I've gathered from my info so far is that something having to do with 4r - 7 and r - 2 = 180. How do I set my problem up from there? (I can figure it out algebraicly when the equasion is set up)
So then, the answers would be , and ? Would it be in degrees?
Another problem:
Two angles are complementary. One angle measures 26 degrees more than the other. Find the measures of the angles.
Erm... I know that one angle is 26 degrees more than the other!...... and I guess complementary angles have a sum of 90 degrees... so how do I set up the problem?
no, the sum of those two angles is greater than 180 degrees, therefore, they are not supplementary as we were told. you did something wrong.
yes. we equated the angles to 180, that means we are working in degrees. if we were working in radians, we would equate them to . besides, it would be clumsy to describe angles so large in radians, a circle has only radians, after all.Would it be in degrees?
Let one of the angles beAnother problem:

Then the other angle is
Since the angles are complimentary, we have:
Now conitnue
so I plugged in that value for and .
My answer is and . I guess that is the answer... thank you!
I think I found the answer to my first problem!! I believe I was doing something wrong in the algebra part...
How I did it with algebra:
Plugging in numbers:
r - 2
37.8 - 2
35.8
4r - 2
4(37.8) - 7
144.2
The sum of those two numbers = 180... so I guess that means they are right!!... Thank you, Jhevon! You're a life saver!

"Jhevon, oh Jehvon! Where arrrrrre yoouuuuu?!"
Lol, question of the night:
If m/ AGB = 4x + 7 and m / EGD = 71, find x.
Find x. Find x. Okaaaaaay. *starts looking around for x...*
The drawing they gave me looks somewhat like this:
Oh yeah, an actual drawing from myself. I feel special.
Please help
and are what we call "opposite [or vertical] angles," these are angles that are opposite each other that are formed by the crossing of two straight lines.
Theorem: Opposite angles are equal
Thus,
Now continue
this reminds me of a joke. see post #39 here. (it is the second to last post on the page, posted by Krizalid)Find x. Find x. Okaaaaaay. *starts looking around for x...*
nice drawing

Wow! A theorm even! Haven't gotten to those beauties yet. Can't wait lol.
x = 16
Lol! How sarcastic! Sarcasm rules... that was hilarious!this reminds me of a joke. see post #39 here.
Thank you for the complimentnice drawing
*sigh* I shall move on to my conjecture problems now. Might need some help with those soon. We'll see.
well, i think it's a theorem.
if you're interested, you can look it up. doing a quick google search on "opposite angles" should give you all the information you need.
correctx = 16
sure thing.Lol! How sarcastic! Sarcasm rules... that was hilarious!
Thank you for the compliment

i should have told you this before, but you should make sure to post new questions in new threads with the appropriate titles. it helps to keep things organized around here. up to now, all your questions have been about angles, so it wasn't that bad, but if the topics deviate vastly, you need a new thread
I'll remember that next time. I'm just used to the way my other forum works... they looove recylcing threads, so I apologize. I'll make a new thread with the right title next time.
... so repetative my post was... lol D. Do you guys white fontitize on here? Oh yeah... it's awesome...... nevermind....
