Question

if sinA+cosA=root2cosA (A not = to 90)then the value of tanA is​

Answer 1

Answer:

sin A +cosA = √2cosA

Step-by-step explanation:

divide the equation by cosA

sinA/cosA + cosA/cosA = √2 cosA/cosA

tanA +1 =√2

tanA=√2-1

Answer 2

Step-by-step explanation:

sin A + cos A = root 2 cos A

or, sin A = root 2 cos A - cos A

or , sin A = ( root 2 - 1 ) cos A

or ,sin A / cos A = ( root 2 - 1 )

or , tan A = ( root 2 - 1 )
