Answer:
6
Step-by-step explanation:
All sides of triangle EFD have x6 of BAC.
E.g.: BA = 2. ED = 2 x 6 = 12
Answer:
x = 15
Step-by-step explanation:
Sides opposite congruent angles are congruent:
x + 10 = 2x - 5
15 = x . . . . . . . . . add 5-x
The value of x is 15.
_____
I suppose you could show the intermediate step:
x +10 +(5 -x) = 2x -5 +(5 -x)
15 = x . . . . . simplified

By definition, the equation of a circle, centered at point (a, b) is

Where r is the radius of the circumference, and is calculated as the distance from the center to any point belonging to the circumference.
We have the center (5, -4) and the point through which the circumference passes (-3, 2), then:

Finally, the equation of the circumference is:
