Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) = 3x-2 and g(x) = 2x+1
<h3>To find </h3>
<h3>Solution</h3>
- (f+g)(x) =
- f(x) + g(x) =
- 3x - 2 + 2x + 1 =
- 5x - 1
Note that 165 deg can be split up into 2 angles: 120 and 45 degrees.
We know (or should know) the sine and cosine values of each of these.
sin (x+y) = sin x cos y + cos x sin y
Here,
sin (165) = sin 120 cos 45 + cos 120 sin 45, or
sin (165) = sqrt(3)/2 * 1/sqrt(2) + 1/2 * 1/sqrt(2)
Finish this work; it will give you the correct answer.

it say the answer is 4 but I don't know how
Answer:
Convert fractions into decimal, round up if the decimal is 0.5 and/or higher, and round down if less than 0.5
Example for question 1: 5/6= 0.83 ← greater than 0.5, so round up to 2
