Question

sin765
$sin(765)$

Answer 1

Sin756

Sin(720+A)=sinA

(Don't have theta key in keyboard
use A in place of that.)

Sin(720+45)=sin45

$\sin45 = \frac{1}{ \sqrt{2} }$


This is ur ans hope it will help you

Answer 2

GIVEN :

• The sin = 765

TO FIND :

• Sin = ?

STEP - BY - STEP EXPLANATION :

=> The 1st Sin = 765 ( given )

=> Sin (720 + ) = Sin A

=> Sin ( 720 + 45 ) = Sin 45

$= >sin \ 45 = \frac{1}{ \sqrt[]{2} }$

Therefore, The 2nd obtained sin = 1/√2
