Answer:
100°
Step-by-step explanation:
Total angle in a triangle is 180
∠C = 180 - 20 - 60
= 180 - 80
= 100
is the polynomial of one variable with second-order and 
is the polynomial of two variables with third-order
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have polynomials:
and
For 
In this polynomial, the number of variables is one and the maximum power of x is 2, therefore:
This is the polynomial of one variable with second order.
In polynomial, there are two variables x and y.
The maximum power of x is 3( x has a power of 2 and y has a power of 1)
This is the polynomial of two variables with third order.
Thus, is the polynomial of one variable with second-order and is the polynomial of two variables with third-order.

Answer:
Step-by-step explanation:
None of the given options as the bottom three are linear and the top one has a vertex at (-3, 4)
If one of the other was SUPPOSED to say ±3(x + 2)² + 4, then I'd choose that one.
