Answer:
20
Step-by-step explanation:
The point of contact of the tangent and the diameter of the circle is a right angle.
Thus the triangle with legs 12 and 2 × 8 = 16 is right
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
? = = 20
2(-2x+4)= -6x+12. ---> -4x+8= -6x+12 ---> combine like terms so +4x to -6x to get 8= -2x+12 ---> -12 on both sides to get -4= -2x --> divide both sides by -2 to get 2= x
