Question

6) If sin(A + B) = 1, cos (A - B) = 1, find A and B (a) A = 60", B = 30° (c) A = 45°, B = 15° (b) A = 45", B = 45° (d) A = 30°, B = 60°

Answer 1

Answer:

b options are correct

Step-by-step explanation:

a=45 and b=45

Answer 2

Answer:

A=45,B=45

sin(a+b)=sinacosb+cosasinb

cos(a-b)=cosacosb+sinasinb
