Answer:
D
Step-by-step explanation:
2 sin²x=sin x
2 sin² x-sin x=0
sin x(2 sin x-1)=0
sin x=0
x=0,π
2 sin x-1=0
2 sin x=1
sin x=1/2= sin π/6,sin (π-π/6)
x=π/6,5π/6

<u>Corrected Question</u>
Points X and Y are endpoints of a diameter of Circle W. Point Z is another point on the circle. Find the probability that
XZY is a right angle.
Answer:
Probability=1
Step-by-step explanation:
<u>Theorem</u>
- If an Inscribed angle intercepts a semicircle, the angle is a right angle.
Given that X and Y are endpoints of a diameter of Circle W and point Z is on the circle's circumference.
I have prepared a diagram which is attached.
Then,
XZY is an angle which intercepts a semicircle.
By the theorem above,
XZY is a right angle.
Therefore, the probability that
XZY is a right angle =1
