The coordinates of point B are (-9, -9)
<h3>Midpoint of Line</h3>
From the question, we are to determine the coordinates of point B
Given a line with endpoints (x₁, y₁) and (x₂, y₂)
The midpoint of the line is ((x₁+x₂)/2 , (y₁+y₂)/2)
Thus,
From the given information,
Midpoint of AB is (-2,-3)
and
A = (5,3)
Let the coordinates of point B be (x₁, y₁)
Then,
-2 = (5 + x₁)/2
-4 = 5 + x₁
x₁ = -4 - 5
x₁ = -9
Also,
-3 = (3 + y₁)/2
-6 = 3 + y₁
y₁ = -6 - 3
y₁ = -9
Hence, the coordinates of point B are (-9, -9)

Answer:
Measure of angle 4 is 115°
Step-by-step explanation:
First, we want to find the measure of angle 2, because the measure of angle 2 is equal to angle 4. When 2 straight lines cross each other, the angles formed are always equal to the angle right across from it.
Find angle 2 by setting up an equation:

This is basically saying that angle 1 plus angle 2 equals 180°. In a half turnaround, the angle is 180°. Angle 1 and 2 make up a half turnaround.
Solve the equation:

Combine the 2 x's to get 2x.

Subtract 50 from both sides.

Divide both sides by 2.

Since x=65, plug 65 into x in the measure of angle 2 (x+50).
65+50=115.
Since Angle 2 is equal to angle 4, angle 4 is also 115.
