Question

if sina+coasa=√2cos a find the value of tana​

Answer 1

sinA + cosA = √2cosA

sinA = √2cosA - cosA

sinA = cosA(√2-1)

sinA/cosA = √2-1

tanA = √2-1

Answer 2

Answer:

root 2 - 1

Step-by-step explanation:

divide the equation by cos a on both sides, you'll get

tana + 1=root 2

=> tan a= root 2- 1
