Assuming both vertical lines are parallel and assuming I'm supposed to find all the unmarked angles...
Angle C:
Supplementary Angles.
x+36=180
180-36=x
x=144
Angle B:
Corresponding Angles.
Angle B ≅ Angle C
144
Angle A:
360 degrees in a quadrilateral
36+144+81+x=360
261+x=360
x = 99

Answer:
Step-by-step explanation:
Notice that:
● 1/2 = 0.5
● 4/5 = 0.8
0.8 is greater than 0.5.
So:
● 0.8 > 0.5
● 4/5 > 1/2
Answer:
Domain: All real numbers
Range: 
Step-by-step explanation:
The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.
The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is 
16x^2-40x+25 Yes I know my phone is messed up but at least you got the answer
The correct answer is B. If you drop the parenthesis and collect like terms you get 8-3i.
