Answer 2

Step-by-step explanation:

sin(A+B)=1 and,

cos(A+B)=1

sin(A+B)=sin 90

A+B=90— (1)

cos(A+B)=cos 0

A+B=90— (2)

Now, eleminating 'B' for finding A

A+B=90

A+B=0

2A=90

A=45

Now,

A+B=90

45+B=90. (putting the value of A in 1)

B=45

The value of A is 45 and the value of B is also 45
