Answer:
x = 3
Step-by-step explanation:
40+ 46x + 2 = 180 degrees
46x = 180 - 42
x = 3
25% should be the answer, let me kno if its correct
Answer:
Its D.
Step-by-step explanation:
All of the other answers don’t make sense and my gut it telling me that its D.
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.
Answer:
A add -9
Step-by-step explanation:
After this you should add -9 to bring it over to the left side.
