The midpoint of overline AB is M(2, -2) If the coordinates of A are (-2, 1), what are the coordinates of B?

Tju [1.3M]

Answer:

(6, -5)

Step-by-step explanation:

Midpoint :

(2, -2) = (x - 2 / 2, y + 1 / 2)

Equations formed :

x - 2 / 2 = 2

x - 2 = 4
x = 6

2. y + 1 / 2 = -2

y + 1 = -4
y = -5

Coordinates of B : (x, y)

(6, -5)

Answer:

x = 16

Step-by-step explanation:

From the first statement, we can say that:

Angle A is equal to angle D,

Angle B is equal to and E.

Since measure of Angle B and E are given and they are equal, we equate them and solve for x.

$B=E\\x+15=6x-65\\15+65=6x-x\\80=5x\\x=\frac{80}{5}\\x=16$

Hence x = 16
