Answer 1

Answer:

Option C is the correct answer....

Step-by-step explanation:

Given that,

Sin(A+B)=1 and,cos(A-B)=1

Apply sin inverse on both sides,

sin^-1(sin(A+B))=sin^-1(1)

A+B=90°

And from second equation,

Apply cos inverse on both sides...

cos^-1(cos(A-B))=cos^-1(1)

A-B=0°

Solve the two equations,

we get,A=B=45°
