Answer:
Step-by-step explanation:
Alright, lets get started.
We have given two points that are end point of diameter.
So, the center point will be :
x co-ordinate :
y co-ordinate :
Hence the center is : (-5,4)
Now the distance between these two end points :
So radius will be half of this diameter.
Plugging these values in standard equation of circle
.................................. This is the answer
Hope it will help :)
Answer:
°
Step-by-step explanation:
"Theorem 9-13: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs."
Basically no matter what other circle, secant or tangent you get, you just use the formula
If you need the outer angle, just put the other angles in and solve
If you need the far or near point angle, re-arrange the formula to get that value.
