Answer:
The equation in standard form is 
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)
The equation in standard form is 
Answer:
(-1, -1/2)
Step-by-step explanation:
M= (Xa+Xb/2, Ya + Yb/2)
M= -11+9/2 , 0 + -1/2
M = -2/2, -1/2
M=(-1, -1/2)
I'm probably wrong but here you go!
Hello!!
Well, the angles in a triangle must add up to 180 degrees.
So, since one angle is 40 degrees, the other two angles must add up to 140 degrees.
A quick look over the answer choices will show that option C, 35 degrees and 105 degrees, is the only possible answer.
Hope this helps!! Let me know if you have ANY questions.
