What is the value of cos0 in the diagram below? URGENT PLS HELP
Accepted Solution
A:
Answer:[tex]\cos\theta=0.6[/tex]Step-by-step explanation:Method 1The given diagram is the unit circle.The terminal side of the angle [tex]\theta[/tex] intersected the unit circle at [tex](0.6,0.8)[/tex].On the unit circle, the cosine of the angle in standard position is the x-value of the point. That is,[tex]cos\theta=x[/tex] The x-value of the given point is [tex]0.6[/tex].[tex]\therefore \cos\theta =0.6[/tex] Method 2See diagram in attachment.[tex]\cos\theta=\frac{adjacent}{hypotenuse}[/tex] [tex]\cos\theta=\frac{0.6}{1}[/tex] [tex]\cos\theta=0.6[/tex]
