Question

if sin
(A + B) = 1 and cos (A - B) = 1,0° < A+B S 90°, find A
If sin (A + B)
B find A and B.
​

Answer 1

Answer:

A=1,B=0

taking A+B=1 and A-B=1( because if we take 0 then value of a will be halved and B will be 1)

elimination method

A+B=1

A-B=1

B gets cancelled a= 1

and when this is transferred to eqn1.

1+B=1

value of B will be 0 as fared.

I hope I helped u much
