I assume it makes a right angle because line AB is tangent. I believe you could solve this using the Pythagoras Theorem.
OpenStudy (liv1234):
Can you help me solve it?
OpenStudy (confluxepic):
Sure. :)

\(\Huge a^2+b^2=c^2\)

So, 6^2+11.7^2=C^2?
OpenStudy (confluxepic):
a and b are the two sides and c is the hypotenuse.
OpenStudy (confluxepic):
a and b are the two sides that make a right angle.
OpenStudy (confluxepic):
AO would be the hypotenuse.
OpenStudy (liv1234):
So, how would I put that into an equation? And by the way, thank you for your help, I appreciate it.(:

a=6 as in the question.
b is unknown.
c is the hypotenuse. In other words it is AO and its value is 11.7 as mentioned in the question.
OpenStudy (liv1234):
Ohh. So, the answer would be 6^2+11.7^2?
OpenStudy (confluxepic):
\(\Huge 6^2+b^2=11.7^2\)
OpenStudy (liv1234):
\[6^2+11^2\]
OpenStudy (liv1234):
oops, I messed up.

I just substituted the values to where they belong.
OpenStudy (liv1234):
Oh, so it would be C?
OpenStudy (confluxepic):
Can you tell me how you got C as the answer?
OpenStudy (liv1234):
Yes, so I put in what 11.7^2 was and got 136.89. Then I put in 6^2+10.0^2 and got 136.
OpenStudy (confluxepic):
Correct but you did it the wrong way. The correct way it to do \(11^2-6^2=x^2\).

Nnesha (nnesha):
|dw:1434216486710:dw|
this straight line add up to 180 degree
Nnesha (nnesha):
set an equation |dw:1434216532709:dw|
\[\huge\rm 50+90+x=180\] solve for x
OpenStudy (liv1234):
@Nnesha I got 230 for the answer, can you help me with another??

impossible !
i told you
straight line add up to 180 degree all 3 angles should add up to 180 degree
OpenStudy (liv1234):
So, 38?
Nnesha (nnesha):
typo it's 92
\[\huge\rm 50+92+x=180\] solve for x
Nnesha (nnesha):
yep
OpenStudy (liv1234):
So, it's 38. And can you help me with another question?
