Step-by-step explanation:
Use calculator:
sin x = 0.4 --> arc
x=23∘58
Trig unit circle gives another arc x that has the same sin value:
x=180−23.58
=156∘42
Answers for (0, 360)
23∘58,156∘42
P(D) = P(C)
We know that in total all (a,b,c,d) equal 1
So .28+.56+C+D=1
We can interpret it as
.84 + 2x = 1
x=.08
So P(D) = .08
