Find the exact value of sin 105 degrees

Step-by-step explanation:

I'm going to write 105 as a sum of numbers on the unit circle.

If I do that, I must use the sum identity for sine.

Plug in the values for sin(60),cos(45), sin(45),cos(60)

Step-by-step explanation:

Note that 105 = 45 + 60.  Therefore,

sin 105 = sin (45 + 60).

The relevant sum formula is

sin (a + b) = sin a cos b + cos a sin b

Therefore,

sin 105 = sin (45 + 60) = sin 45 cos 60 + cos 45 sin 60, or

                                     = (1 / √2)(1 / 2)        + (1 / √2)(√3 / 2)

                                          1 + √3

                                     =

                                            2√2

step-by-step explanation:

cougars 12/10 (12-10 = 2)

bobcats 20/10 (20-10 =10)

bulldogs 8/5 (8-5 =3)

tigers 3/5 (3-5 =-2)

answer: i think one of the answer is $150 and $300?
