What is the value of y if the segment outside the circle is tangent to the circle?
2 answers:
Answer: B : 95°
Step-by-step explanation:
Since, the measurement of an angle formed by a chord and a tangent that intersect on a circle, is half the measure of the intercepted arc.
In the given diagram, the intercepted angle = 360° - 170° = 190°,
Hence, by the above definition,
Thus, the measurement of angle y = 95°
⇒ Option B is correct.

Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).
Then the hypotenuse length is √(1+4²) = √17.
The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so
