Answer:
The answer to your question is ( -7/10, -4 7/10)
Step-by-step explanation:
Data
Enpoint (3/2, 1 1/2) x1 = 3/2 y1 = 1 1/2
Midpoint (2/5, -8/5) xm = 2/5 ym = -8/5
Entpoint 2 ( x, y)
Formula
Xm = (x1 + x2)/2 Solve for x2 x2 = 2xm - x1
Ym = (y1 + y2)/2 Solve for y2 y2 = 2ym - y1
Substitution
x2 = 2(2/5) - 3/2
x2 = 4/5 - 3/2
x2 = (8 - 15)/10
x2 = -7/10
y2 = 2(-8/5) - 1 1/2
y2 = -16/5 - 3/2
y2 = (-32 - 15) / 10
y2 = -47/10 = -4 7/10
All quadrilaterals have a total of 360 degrees so...
90+76=163
163+111=274
360-274=86
The measurement for the 4th angle would be 86 degrees
