The value of CosA is 0.8191
Step-by-step explanation:
Given SinA= 0.5736
We know that [tex]SinA^{2} + CosA^{2} = 1[/tex]
Replacing value of SinA,
[tex](0.5736)^{2} + CosA^{2} = 1[/tex]
[tex](0.3290) + CosA^{2} = 1[/tex]
[tex] CosA^{2} = 1-0.3290[/tex]
[tex] CosA^{2} = 0.6709 [/tex]
[tex] CosA = 0.8191 [/tex]
The value of CosA is 0.8191
