Answer:
x = 60°
Step-by-step explanation:
AOB Center: O AB: diameter
arc ADB = 180°
arc DB = 180 - arc AD = 80°
x = 1/2 x ( arc DB + arc AC) = 1/2 x (80 + 40) = 60°
240 is the correct answer.
The polynomial with 4 turning points has the degree of 4+1 = 5. Whatever number of turning points there are, add 1 and you get the degree.
The degree of the polynomial with one root or zero is 1
When you multiply polynomials, the degrees will add so 5+1 = 6 is the minimum degree of the new polynomial.
The final answer is 6.
The absolute value of a quantity is 5 if that quantity is either 5 or -5.
So, the two solutions are


Now, there is a bit of ambiguity here: we are not told who
and
are exactly, and yet the value of
depends on our choice.
If we choose a = 2 and b = -3, then the value of a-b is 5
If we choose a = -3 and b = 2, then the value of a-b is -5
