Determine if line AB is tangent to the circle. Please help!!
Ugo [173]

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

12 {}^{2}  + 16 {}^{2}  = 20 { }^{2}  \\ 144 + 256 = 400 \\ 400 = 400

it proves that it's a right angled triangle. Hence AB is a tangent to circle.

Why in division there is sometimes remaindres?
Ksenya-84 [330]
In division problems, if the division results in a decimal or fraction, (not a whole number), than it has a remainder.  If the division results in a whole number, then there is no remainder, or a remainder of zero. 

Examples:

6/3=2

6/4=1.5
