Answer: Z'(-7;8)
suppose the coordinates of Z' is Z'(x,y)
we have:
=> Z'(-7;8)

Step-by-step explanation:
If AB is a tangent then ∠ ABC = 90° and Δ ABC is right
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides.
15 is the longest side and 15² = 225
9² + 12² = 81 + 144 = 225
Thus Δ ABC is a right triangle at B
Thus AB is a tangent to the circle at B
I believe that the answer is the first one
Answer:
Step-by-step explanation:
DE*s=BA 24*s=35 s=35/24
(3x+7)35/24=6x-5
35/8x+5/24=6x-5
-5/24 -5/24
