1.	2 sin 65° cos 25° =____________________
Answer» ong>Answer: $2 {<klux>SIN</klux>}^{2} (65)$ Step-by-step explanation: because cos(25) = cos(90-65) we know that cos(90-Φ) = sin(Φ) then cos(25) = cos(90-65) = sin(65) then 2sin(65)cos(25) = $2 {sin}^{2} (65)$ Please MARK me as brainliest if it is correct.

ong>Answer:

$2 {<klux>SIN</klux>}^{2} (65)$

Step-by-step explanation:

because

cos(25) = cos(90-65)

we know that cos(90-Φ) = sin(Φ)

then cos(25) = cos(90-65) = sin(65)

then

2sin(65)cos(25)

$2 {sin}^{2} (65)$

Please MARK me as brainliest if it is correct.
