sin 25°​

Answer 1

Answer:

ThanksA2,

It is given that (sin 65/cos25) + (cos32/sin58 )- (sin28*sec62) + (cosec30*cosec30)

Here (sin 65/cos25) = (sin(90–25)/cos25) = cos25/cos25=1,

(cos32/sin58 ) = (cos32/sin(90–32)) = cos32/cos32 = 1,

sin28*sec62 = sin28*sec(90–28) = sin28*cosec28 = 1,

cosec30 = 2

so put the values in equation,

= 1+1–1+2*2

=1+1–1+4

=5

Finally the ans is 5.

Best regards!!!!!
