Question

if sin(X) = 5/13, then cos(X) = *
answer the question ​

Answer 1

If sinx = 5/13

If sinx = 5/13then squaring both side,

If sinx = 5/13then squaring both side,sin²x= 1-cos²x= 25/169

If sinx = 5/13then squaring both side,sin²x= 1-cos²x= 25/169Or cos²x= 144/169

If sinx = 5/13then squaring both side,sin²x= 1-cos²x= 25/169Or cos²x= 144/169Or cos x= 12/13

If sinx = 5/13then squaring both side,sin²x= 1-cos²x= 25/169Or cos²x= 144/169Or cos x= 12/13Ans.12/13

If sinx = 5/13then squaring both side,sin²x= 1-cos²x= 25/169Or cos²x= 144/169Or cos x= 12/13Ans.12/13 I hope, It was helpful to you
