It is Polaris. You are welcome.
I might be wrong.
Answer:
(x-9)^2 + (y-9)^2 = 81
<u>Step-by-step explanation:</u>
<u>Step-by-step explanation:Equation of a circle</u>
( x - h )<em>^2 + </em>( y - k )<em>^2 = </em>r^<em>2 </em>
Your graph - the circle intersects the x-axis at (9 , -9)
- the circle intersects the y-axis at (9 , -9)
h = the number on the x axis intersected by the circle.
k = the number on the y axis intersected by the circle.
r = radius of the circle measured starting from the origin.
plug these in:
( x - h )^2 + ( y - k )^2 = r^2.
(x - 9)^2 + (y - 9)^2 = 9^2
(x-9)^2 + (y-9)^2 = 81
Answer:
x = 8.4
Step-by-step explanation:
In a right triangle, an angle, the length of its adjacent side and the length of the hypotenuse can be related by the cosine.
In this question:
Angle of 40º.
Adjacent side of x, hypotenuse of 11. So
Using a calculator, we have that 
. So
The answer is x = 8.4
