Step-by-step explanation:
Let the midpoint formula be expressed as;
M(X,Y) = {x2+x1/2, y2+y1/2}
X = x2+x1/2
Y = y2+y1/2
Get x2
-3 = x2 + 1/2
-6 = x2 + 1
x2 = -6-1
x2 = -7
Get y2;
Y = y2+y1/2
8 = y2+6/2
16 = y2+6
Y2 = 16-6
y2 = 10
hence the coordinate of B is (-7, 10). Option A is correct
The answer is D.
Since the two triangles are congruent, they would have equal angles.
The reason why the other answer choices are wrong...
A) ∠S is equal to ∠Y, not ∠Z.
The angle that is equal to ∠Z is ∠T.
B) Line ST is equal to Line YZ, not Line XZ.
The Line that is equal to Line XZ is Line RT.
C) Line RS is equal to Line XY, not Line ST.
The Line that is equal to Line ST is Line YZ.

Answer:
2144.66
Step-by-step explanation:
Make x the same in both so
12x+ 4y=72
12x+6y=30
Now the 12x cancel eachother out so
Difference between 6y and 4y is 2y
Difference between 30 and 72 is -42
2y must equal -42
Y = -21
Substitute -21 into the equation
X = 13
