Answer:
105°
Step-by-step explanation:
This is most likely the answer if the lines are perpendicular... But if It doesn't give you an image of the 2 angles, then the answer is 105°
Answer:
82,5
Step-by-step explanation:


That graph seems to be complementary since both angles sum up to be 180 degrees.
Answer:
Polynomials of degree 8 have exactly 8 roots
Step-by-step explanation:
The Fundamental Theorem of Algebra states that every polynomial of degree n
with
has exactly n roots.
But the roots may be complex numbers.
In your case n=8, so polynomials of degree 8 have exactly 8 roots.
The roots need not be different.
For example, for the polynomial
x=2 is root twice.
