Let x represent the measure of an acute angle of a right triangle. suppose that sin (x) = 7⁄10 . find tan (x) and cos (x).

X represent an acute angle. So x < 90. So it means it is in first quadrant. So value of cos (x) and tan (x) are positive.

Sin(x) = 

We can find cos(x) as by identity which is given as below:


                  = 
                  =
                  = 
So cos(x) = 
 
 As we know 

                 = 
                 

So tan(x) =
