probability of both : 1/3 * 2/7 = 2/21 <==

Answer:
Step-by-step explanation:
Since you are reflecting about the x axis you keep the x coordinate the same and multiply the y coordinate by -1 so you have point (8,-4)
Cos(B) = adjacent / hypotenuse
Cos(B) = 11/27
Cos(B) = 0.4074
B = Cos-1(0.4074)
Put this into your calculator like this.
2nd function Cos-1
