Math Question

[darkzelkova]

So I got a math question the other day, and I haven't been able to figure it out. Anyone got any idea how I could do it?

Here it is: Point A and point B are the origins of their respective circles. CAE and CBF are line segments. Angle F is 78 degrees (how do I do that little symbol?), What is the measure of angle C?

Any help would be greatly appreciated!

EDIT: Sorry about that, I did mean origin of the circle

 

[Jokerman5656]

do you mean that points A and B are origins of their respective circles, not triangles?

 

[spdcbr]

I got it, judging by the circle, it's equal to angle F. So...

180-78+78=24 degrees.
.......(156).................

Mwaahahaa! I solved it! Point A and B is there to confuse you.

 

[Jokerman5656]

i dont think the answer is a fart piece of cow **** that sucks ****. so your wrong

 

[spdcbr]

I say they answer is pi........ MeMyselfandPi to be precise

What th-
I ALRREADYY SOOLVEDD IT!!!! I DID ITTT!NOT PIIIII! NOT PIIIII! NOT MEMYSELFANDPI!!!!!!NO!!!!!!IT 24!!!

"180-78+78=24 degrees"
Bad math... that equals precisely 180 degrees.

Your faulty math aside, please explain this statement.

 

[blah]

x + 2x + 78 + 78 = 180
x = 8

 

[chencube]

x + 2x + 78 + 78 = 180
x = 8

This is right.

 

[Lord Voldemort]

Which angles do x and 2x represent?

 

[blah]

Let the point on the line segment AE where the circle B intercepts the triangle be point Z, and the point on line segment BC on circle A be point Y. First, draw line segment AB. AB is a radius of circle A. It is also a radius of circle B. If the same line segment is the radius of two circles, then the radius of the circles must be equal.

Your point being?

"180-78+78=24 degrees"
Bad math... that equals precisely 180 degrees.

Uhhh...you take away from 180 and you get precisely 180?

 

[spdcbr]

x + 2x + 78 + 78 = 180
x = 8

Sigh, this is wrong, 2x is just a distraction.

I got 8 also, my way was much more complex and involved drawing two radii from B to make two more triangles and using the arcs of the circle on the right. If anyone wants me to explain the way I did it, I can. But that really shouldn't be necessary.

spdcbr, shut up.

Uhhh...you take away from 180 and you get precisely 180?

You subtracted from 180, and then added back what you subtracted.

Learn order of operations, please.

Let's slow this down for you...

180-78=102
102+78=180
NOT 24.

 

[Lord Voldemort]

Let the point on the line segment AE where the circle B intercepts the triangle be point Z, and the point on line segment BC on circle A be point Y. First, draw line segment AB. AB is a radius of circle A. It is also a radius of circle B. If the same line segment is the radius of two circles, then the radius of the circles must be equal.

Your point being?

I needed to get another look at the diagram, so I posted it without finishing. Then I realized that where I was going was wrong.

"180-78+78=24 degrees"
Bad math... that equals precisely 180 degrees.

Uhhh...you take away from 180 and you get precisely 180?

Uhh... You forgot parenthesis...

x + 2x + 78 + 78 = 180
x = 8

Sigh, this is wrong, 2x is just a distraction.

I thought so...

 

[spdcbr]

I meant this:

180-(78+78)=24
Okay? get it?

 

[chencube]

Which angles do x and 2x represent?

x = Angle C.
2x = Angle CEB

Just draw a line from A to B you will see how easy it is.
