The explicit formula
First, calculate 
Set n=2; So:
Substitute -25 for 
Calculate the common difference (d)
So, the nth term is:
Open bracket
Collect like terms
If I follow the angle degrees that they gave, your answers would be as follows:
I=145°
S=155° or 90°
E=78°
L=120° or 55°
Maybe this is right, sorry it took so long.
Yeah they have both the same products. if u look at how many 0 the have u would be ever to tell that it would equal 28000

lol
Step-by-step explanation:
Well knowing that the terminal arm of the standard position angle is in quadrant 2, we can determine the reference angle, in quadrant 2, by simply taking the difference between 180 and whatever the angle is.
So ø reference = 180 - ø in standard position.
Regardless, the reference angle is in quadrant 2, we need to then label the sides of the reference triangle based on the opposite and hypotenuse.
Solve for adjacent side using Pythagoras theorem.
A^2 = C^2 - B^2
A^2 = 3^2 - 2^2
A^2 = 9 - 4
A^2 =5
A = sq root of 5.
Then write the cos ratio using the new side.
Cos ø =✔️5/3. Place a negative in front of cos ø as cos is negative in second quadrant.
