Step-by-step explanation:
A unit circle is one whose radius is 1
sin(90) will have coordinates (0,1)
sin(40)= 0.643
sin(40)= P/H= 0.643/1
cos(40)= B/H= 0.766
Similarly for cos(245)= cos(-65)= -0.423/1
sin(245)= sin(-65)= -0.906
Irrational numbers have a long amount of numbers after the decimal place that never really end it would be like pi or the square root of two. Also irrational numbers can't be represented as a fraction
