Cos(x)= 40/41 and x lies in Q4. Find sin(x)

notka56 [123]

Step-by-step explanation:

$\sin(x) = \sqrt{1 - {cos}^{2}x }$

$\sin(x ) = \sqrt{1 - { (\frac{40}{41} )}^{2} }$

$\sin(x) = \sqrt{ \frac{1681 - 1600}{1681} } = \sqrt{ \frac{81}{1681} }$

sin(x)=±9/41

As x lies in Quadrant 4 , sin(x) = -9/41
