PLEASE HELP!! Condense and evaluate the following expressions using identities: 1. cos pi/3 * cos (5pi)/6 - sin pi/3 * sin (5pi)/6

3. (tan 122 degrees - tan 32 degrees)/(1 + tan 122 degrees * tan 32 degrees)

4. 2sin 15 degrees * cos 15 degrees
You don’t have to answer all of them but it would be cool

25% is the answer

21

jk it's 20

step-by-step explanation:

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder
