Geometry help

OpenStudy (anonymous):

What is the measure of E, in degrees?|dw:1366724782359:dw|

OpenStudy (anonymous):

ahahahaha isosceles triangle ^.^

OpenStudy (nathan917):

Yes..

OpenStudy (anonymous):

I suck with geometry lol

OpenStudy (anonymous):

You know isosceles triangles would have a pair of congruent angles at the base, right? |dw:1366724933303:dw|

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

Her???! Nathan, this is a boy :P

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

LOL Fradycat what a silly name :D Anyway, when you add up all the angles of a triangle (any triangle, really) they'd always add up to 180 degrees ^.^

OpenStudy (nathan917):

Yes.

OpenStudy (anonymous):

Yeah then you subtract what you get from 180?

terenzreignz (terenzreignz):

I didn't take you for a geometer, Pan...

OpenStudy (anonymous):

yup... so what do you subtract from 180? @teri LOL

OpenStudy (anonymous):

96

terenzreignz (terenzreignz):

Nice.

OpenStudy (anonymous):

Then i get 84

OpenStudy (anonymous):

And so your final answer is...?

OpenStudy (anonymous):

AWESOME!!!!!!!

terenzreignz (terenzreignz):

Overreacting as always...

OpenStudy (anonymous):

What is the measure of C, in degrees? |dw:1366725220111:dw|

terenzreignz (terenzreignz):

Equilateral triangles are also Equiangular...

OpenStudy (anonymous):

iS THE ANSWER 60?

terenzreignz (terenzreignz):

Yup.

terenzreignz (terenzreignz):

That holds true for all triangles that are equilateral.

OpenStudy (anonymous):

What is the length of ? |dw:1366725377175:dw|

OpenStudy (anonymous):

length of what? o.O

OpenStudy (anonymous):

MN

OpenStudy (anonymous):

It's isosceles, isn't it? So 3x = x + 8 and solve ^.^

OpenStudy (anonymous):

7

OpenStudy (anonymous):

Nope... try again :D What's x?

OpenStudy (anonymous):

5

OpenStudy (anonymous):

still no. Are you guessing? LOL

OpenStudy (anonymous):

3

OpenStudy (anonymous):

That's the third guess... and it's still wrong... c'mon, just solve 3x = x + 8 :)

OpenStudy (anonymous):

idk

OpenStudy (anonymous):

4

OpenStudy (anonymous):

That's much better. :) So since x = 4 What's the length of MN?

OpenStudy (anonymous):

4

terenzreignz (terenzreignz):

No... MN is x + 8

terenzreignz (terenzreignz):

So just plug in your value for x.

OpenStudy (anonymous):

Aww, I wasn't done, @teri :(

terenzreignz (terenzreignz):

Sucks to be you :P

terenzreignz (terenzreignz):

So what's x + 8 when x = 4? @Fradycat

OpenStudy (anonymous):

12

terenzreignz (terenzreignz):

That's it.

OpenStudy (anonymous):

The Isosceles Triangle Theorem states that if two sides of a triangle are congruent, then the angles _____________ those sides are congruent.

OpenStudy (anonymous):

Didn't I already mention this? Look back to the first question we answered :)

terenzreignz (terenzreignz):

Opposite. It's opposite.

OpenStudy (anonymous):

thnx

OpenStudy (anonymous):

You take away all the fun @Terence >:(

OpenStudy (anonymous):

whoopsie, tagged someone I don't know lol @terenzreignz
