Answer 1

Answer:

a

Step-by-step explanation:

1. sinA + cosA=root2 cosA both side divide by cosA

sinA + cosA == root2 cosA

tanA +1= root 2

tanA==root2-1. {A=theth}

Answer 2

Answer:

√2-1

Step-by-step explanation:

Given,

sinø+cosø=√2cosø

sinø+cosø/cosø=√2

sinø/cosø+cosø/cosø=√2

tanø+1=√2

tanø=√2-1
