Question

evaluate these answer​

Answer 1

Answer:

Yes

Step-by-step explanation:

Sin Sq (90-27)+sin Sq 27°upon cos Sq (90-73)+cos Sq 73°

=cos Sq 27°+sin Sq 27°upon sin Sq 73°+cos Sq 73°

1/1 (as cos Sq A +sin Sq A =1)

1

Answer 2

Step-by-step explanation:

1-=sin^2 63+cos^2(90-27)/cos^2 17+sin^2(90-73)

=sin^2 63+cos^2 63/cos^2 17+sin^2 17

=1/1

=1

2-=sin 25×sin(90-65)+cos 25×cos (90-65)

=sin 25×sin 25+cos 25×cos 25

=sin^2 25+cos^2 25

=1
