AB is tangent to O. If AO=12 and BC=25 what is AB ? The diagram is not to scale.
Marat540 [252]
The answer is A


AO = 12

BC= 25+ 12= 37
you can get help from Pythagoras theorem
{37}^{2} =  {12}^{2}  +  {x}^{2}  \\  -  {x}^{2}  =  {12}^{2}    -   {37}^{2}  \\  -  {x}^{2}  = 144 - 1369 = -  1225 \\1225 =  {x}^{2}
x =  \sqrt{1225}  = 35
