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
Pretty sure it’s the first one
Answer:
c) 9
Step-by-step explanation:
4x - 2 + 30 = 64
4x + 28 = 64
4x = 64 - 28
4x = 36
x = 36/4
x = 9
