the degree of the polynomial would be 10.
Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
Value of cos(x+π) =
Given cosine of x =
i.e., cos(x) =
Also cos() = . So x = .
We need to find cos(x+π) = cos().
But its value is not easy to find. So we use trigonometric formulas.
We have the trigonometric formula, cos (x+π) = - cos(x) = - =
Cos(x+π) lies in the 3rd quadrant. So there cosine has negative values. That is why, cos (x+π) = - cos(x).

Answer:ok
Step-by-step explanation:
If we us the method asquared + b squared =c squared x=8 cuz
8*8=64
6*6=36
36+64=100
and 10*10 =100
so x=8
hope this helps
