Answer:
Centre = (-2,7) B
radius = 6
Step-by-step explanation:
The general formula for finding the equation of a circle is expressed as shown:
(x-h)²+(y-k)² = r² where (a,b) is the centre and r is the radius of the circle
Given the equation of the circle C in question (x+2)²+(y−7)²=36. We will compare the given equation to the general equation.
On comparison;
-h = 2
h = -2
-k = -7
k = 7
r² = 36
r = √36
r = ±6
From the answers gotten, it can be inferred that the centre of the circle (h,k) is (-2,7) and the radius of the circle is 6.
Radius of a circle cannot be a negative value so we will ignore the negative value of 6.
Sinα=(opposite side)/hypotenuse
cosα=(adjacent side)/hypotenuse
tanα=(opposite side)/(adjacent side)
In a right triangle the longest side is the hypotenuse.
If one angle opposite a side is α, the angle opposite the other side is 90-α (because the sum of all angles must be 180° for any triangle)
I hope that helps as your question is not really clear, if you have any more specific questions, I'd be happy to help out. :)
u=60° as it is an equilateral triangle
Answer:
-2 1/3, -5/2, 1/16, 16
The more negative the number gets, the lesser it would be.
I got b i did this question before but dont take my word for it im not one hundred percent sure
