I assume it makes a right angle because line AB is tangent. I believe you could solve this using the Pythagoras Theorem.

- Liv1234

Can you help me solve it?

Sure. :)

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

- Liv1234

So, 6^2+11.7^2=C^2?

- confluxepic

a and b are the two sides and c is the hypotenuse.

- confluxepic

a and b are the two sides that make a right angle.

- confluxepic

AO would be the hypotenuse.

- Liv1234

So, how would I put that into an equation? And by the way, thank you for your help, I appreciate it.(:

- confluxepic

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.

- Liv1234

Ohh. So, the answer would be 6^2+11.7^2?

- confluxepic

\(\Huge 6^2+b^2=11.7^2\)

- Liv1234

\[6^2+11^2\]

- Liv1234

oops, I messed up.

- confluxepic

I just substituted the values to where they belong.

- Liv1234

Oh, so it would be C?

- confluxepic

Can you tell me how you got C as the answer?

- 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.

- confluxepic

Correct but you did it the wrong way. The correct way it to do \(11^2-6^2=x^2\).

|dw:1434216486710:dw|
this straight line add up to 180 degree

- Nnesha

set an equation |dw:1434216532709:dw|
\[\huge\rm 50+90+x=180\] solve for x

- Liv1234

@Nnesha I got 230 for the answer, can you help me with another??

- Nnesha

impossible !
i told you
straight line add up to 180 degree all 3 angles should add up to 180 degree

- Liv1234

So, 38?

- Nnesha

typo it's 92
\[\huge\rm 50+92+x=180\] solve for x

- Nnesha

yep

- Liv1234

So, it's 38. And can you help me with another question?

- Nnesha

i'll try
