Answer:
B. Tangent
Step-by-step explanation:
Tangent always makes 90 degree angle with the radius. Now in triangle let's see if it's right angled triangle or not.
To confirm if it's a right angled triangle it should follow Pythagoras Theorem.
Which states square of hypotenuse = sum of squares of other two legs

it proves that it's a right angled triangle. Hence AB is a tangent to circle.
After a thorough research, there exists the same question that has the following choices.
A. 6.29
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>
The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57
Area of a Triangle Formula:
A=(1/2)base*height
A=54
base=12
Fill in
54=(1/2)*12*h
Solve for h
