Answer:
the angle of 3 is 50
Step-by-step explanation:
What you would do is add 90 to 40 which would get you 130. Then you will subtract 130 from 180 which gets you 50 for angle 1. Since angle 1 is across from angle 3, angle 3 will also be 50.
Answer:
Let's denote: A(-4, 5), B(7, -9).
If P(x, y) is the midpoint of AB, then we have:
x = (-4 + 7)/2 =3/2
y = (5 + (-9))/2 = -2
=> P(3/2, -2)
