Answer:
Option c (7.8) is the correct alternative.
Step-by-step explanation:
The given points are:
(x₁, y₁) = (2, -3)
(x₂, y₂) = (-4, 2)
As we know,
The distance between two points will be:
= 
On substituting the values, we get
= 
= 
= 
= 
= 
= 
After using distributive property and combining like terms the answer is -2
AC would be double of its angle, which happens to be 58.
58•2 = 116.
Therefore, your answer would be D: 116 degrees.
