Question

Firstly: Thanks to the brilliant guys who helped me with my last Geo-related question, @some_someone and @RadEn and @ajprincess.

Well, I have another one.
Yikes.

As I always say: I don't want to know the answer, I want to know how to do these types of problems.
My mind is sort of confused about this one.

And with a horrible teacher, things sure don't get any better.

How would you do this type of problem?

Find the measures of x and y.

Geo never fails to confuse me.
*sigh*

Answer 1

this is an isosceles triangles, so the base angles are congruent

Answer 2

this means x = y

Answer 3

all 3 angles must add to 180 degrees, so

x+y+30 = 180

x+x+30 = 180 ... replace y with x (since x = y)

solve for x

Answer 4

x2+30 = 180 right ?
So I do... wait up.


So I do 2x = 180-30

so that's 150.

I divide by two...

That's... 75 ?
so the answer is 75 ?

Answer 5

yep, x = 75, so y = 75 since x = y

Answer 6

btw I would write x2 as 2x since x2 is easily confused with x^2

Answer 7

oh, right.

Answer 8

Thanks :D

What I can't believe it how many people you help.
And how many fans you have xD

But actually, I help quite a few people in the Computer Science department, particularly the web and server programming languages. I also program a couple of Chrome extensions for OpenStudy.

But math is greek to me as of now. That's bud. :)
I dream of the day I'll reach 99 SS!

Answer 11

Do you happen to have heard of TUOSA?

Answer 12

I've only been over there a couple of times, but don't know much about CS

Answer 13

Answer 14

That's mainly how I've contributed to OpenStudy.
