Question

evaluate sin 25 degree cos 65 degree + cos 25 degree sin 65 degree​

Answer 1

Step-by-step explanation:

$heloo... \\ \\ \sin(25) \cos(65) + \cos(25) \sin(65) \\ this \: is \: nothing \: but \: \\ \sin(a + b) = \sin(a) \cos(b) + \cos(a) \sin(b) \\ \\ above \: experssion \: implies = > \\ \sin(65 + 25) \\ \sin(90) \\ 1 \\ \\ \\ hope \: it \: helps \: uh....$

Answer 2

Answer:

answer is 0

Step-by-step explanation:

sin 25=cos 65

sin 65=cos 25

now,

cos65cos65+cos 25cco25

cos90+cos90

0+0= 0

i hope this is helpfull
