Answer:
actually what is this is you is this a geometry, trigonometry I don't know what to call
Step-by-step explanation:
sinx = a/b
tanx= a/c
cosx= c/b
-19 is the answer ////////////////// sorry i needed more charecters to answer
THe number on the bottom is called the Notation
Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides

r=5
