Question

Evaluate Sin8ºCos82° + Sin82ºCos8°
Sin8ºCos82° + Sin82ºCos8º ​

Answer 1

Answer:

1

Step-by-step explanation:

sin8°.sin(90°-82°)+cos(90°-82°).cos8°

=sin8°.sin8°+cos8°.cos8°

=sin²8°+cos²8°

=1

Answer 2

Answer:

2

Step-by-step explanation:

sin 8 is what u write as cos 82 right? then cos times cos would leave u with cos squared 82 cos 8 could be written as sin 82 and that again goes like sin squared 82. so add them up you get 1 the other one is similar
