The equation for any circle centered at the origin with a radius r is the following:

By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.
Thus, r=5.
This makes the equation:


That should be your answer, let me know if this is confusing in any way.
Happy Studying~
x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees
Answer:
25 inches^2
Step-by-step explanation:
The formula for the area of a triangle is A = (1/2)(base)(height).
Here the base, b, is 10 inches and the height, h, is 5 inches.
Thus, the area of this triangle is
A = (1/2)(base)(height) = (1/2)(10 inches)(5 inches) = 25 inches^2
Answer:
m = 
Step-by-step explanation:
Given
+
= 
Multiply through by 15 to clear the fractions
15 is the lowest common multiple of 3, 5 and 15
10 + 9m = 31 ( subtract 10 from both sides )
9m = 21 ( divide both sides by 9 )
m =
= 
I hope u feeling better but the answer is
