Answer 2

Answer:

LHS. (sinA - sinB)(sinA + sinB) + (cosA - cosB)(cosA + cosB) / (cosA + cosB)(sinA + sinB)

(sin²A - sin²B + cos²A - cos²B) / (cosA + cosB)(sinA + sinB)

sin²A + cos²A - (sin²B + cos²B) / (cosA + cosB)(sinA + sinB)

1 - 1 / (cosA + cosB)(sinA + sinB)

0 / (cosA + cosB)(sinA + sinB)

0

LHS = RHS

plss mark me at brainliest..
