= - 
It’s b ok I got you ok!!!!
Answer:
0
Step-by-step explanation:
Use the hint lol
Step 1: Plug in -2 into the equation.
f(-2) = 4(-2) + 8
Step 2: Multiply
f(-2) = -8 + 8
Step 3: Add
f(-2) = 0
There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
