Answer 1

A=45° and B=45°.

HOPE MY ANSWERS ARE CORRECT.

Answer 2

EXPLANATION.

⇒ sin(A + B) = 1. - - - - - (1).

⇒ cos(A - B) = 1. - - - - - (2).

As we know that,

⇒ sin(A + B) = sin(90°). - - - - - (1).

⇒ cos(A - B) = cos(0°). - - - - - (2).

We can write equation as, we get.

⇒ A + B = 90°. - - - - - (1).

⇒ A - B = 0°. - - - - - (2).

We get,

⇒ 2A = 90°.

⇒ A = 45°.

Put the values of A = 45° in equation (1), we get.

⇒ 45° + B = 90°.

⇒ B = 90° - 45°.

⇒ B = 45°.

Values of A = 45° & B = 45°.
