Answer:
AC=13.6
Step-by-step explanation:
let the triangle is ABC
radius =6 , diameter =6*2=12
therefore AB=12
since BC is a tangent
therefore angle B =90 degrees
BC=6.4
AC=13.6
This equation has the next form:
To find if the equation has two complex solutions we have to check if the discriminant is negative, as follows:
Then, the first case has two complex solutions.
In the second case,
The discriminant in this case is:
Then, the second case has two complex solutions.
In the third case,
The discriminant in this case is:
Then, the third case has two real solutions.
In the fourth case,
The discriminant in this case is:
Then, the fourth case has two complex solutions.
