Answer:
>180° (more than 180°)
Step-by-step explanation:
Angles are classified as ...
- acute: < 90°
- right: = 90°
- obtuse: > 90°
- straight/linear: = 180°
- reflex: > 180°
It seems that we're looking at definitions:
obtuse : >90° :: reflex : >180°
The factor from the provided expression of the variable x and y is taken out. The resultant expression is -1/4(2x-5y).
<h3>What is a factor of equation?</h3>
The factor of a equation is the terms or number which is common in all the terms of the that equation.
The first term of the equation is,
-1/2x
Multiply with 2 in numerator and denominator of this term as,
-2/4x
(-1/4)2x
Now the second term of the equation is,
-5/4y
Rewrite this term as,
(-1/4)5y
Thus, the expression become,
1/2x - 5/4y
(-1/4)2x- (-1/4)5y
-1/4(2x-5y)
Hence, the factor from the provided expression of the variable x and y is taken out. The resultant expression is -1/4(2x-5y).

This is already a whole number
The standard form of a cosine function is 
Where A Amplitude (height), b is period, C is phase shift, D is vertical shift. We are given the Amplitude, Period and Midline. Midline means the same as phase shift. So, the function formed will be
