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

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

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

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

    AO would be the hypotenuse.

    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.

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

    I just substituted the values to where they belong.

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

    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.

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