Answer:
=60 the second option.
Step-by-step explanation:
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a 
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°

Answer:
B and D
Step-by-step explanation:
plug in the x and y for the x and y in the equation
if the two sides come out equal to eachother they satify the function
if they dont well they dont satisfy the function
