Question

If sin(A+B) = 1, cos(A-B) = 1 and A is greater than B and A + B = 90°.


find A and B.

Answer 1

Answer:

A=45 B=45...........................

Answer 2

Step-by-step explanation:

Sin (A+B) =1

Sin (A+B) = Sin 90°

A+B = 90°..... (i)

Cos (A- B) =1

Cos (A- B) =Cos 0°

A - B = 0°......(ii)

Solving equations (i) and (ii), we find:

2A = 90°

A = 45° & B = 45°
