Question

If Sin A = 0.5736, what is the Cos A =

Answer 1

The value of CosA is 0.8191

Step-by-step explanation:

Given SinA= 0.5736

We know that $SinA^{2} + CosA^{2} = 1$

Replacing value of SinA,

$(0.5736)^{2} + CosA^{2} = 1$

$(0.3290) + CosA^{2} = 1$

$CosA^{2} = 1-0.3290$

$CosA^{2} = 0.6709$

$CosA = 0.8191$

The value of CosA is 0.8191
