Question

If cos A = 21/29
Find sin A + tan A

Answer 1

This may be the answer for the given question

Answer 2

${\huge {\mathfrak {Answer :-}}}$

cos A = 21/29

So, sin A = ( 1 - 21^2/29^2 )^1/2

= (1 - 441/841)^1/2

= (400/841)^1/2

= 20/29

And tan A = sin A / cos A

= 20/21

So, sin A + tan A

= 20/29 + 20/21

= 1000/609
