Answer:
y=3x-1
Step-by-step explanation:
1) It is given that line AB is tangent to the circle at A.
∴ ∠CAB = 90º (Tangent at any point of a circle is perpendicular to the radius throught the point of contact)
Thus, the measure of ∠CAB is 90º.
9 times 10 is 90.
90 is 1/10 of 900.
The answer is 9.
you can use either or for the last one
