Answer:
The three planes of motion are the sagittal, coronal (or frontal) and transverse planes.
Sagittal Plane: Cuts the body into left and right halves. Forward and backward movements.
Coronal (or Frontal Plane): Cuts the body into front and back halves. ...
Transverse Plane: Cuts the body into top and bottom halves.
Firstly, you've got to expand the brackets, this becomes;
8a-4= -10a+ 50
You've then got to eliminate the -10a and you do this by adding 10a to both sides,
This then becomes 18a-4=50
You've then got to add 4, to eliminate this, which then becomes 18a=54
You've then got to divide both sides by 18, and this becomes 3.
Therefor, a=3
Hope this helps :)
Answer:
The correct answer is B
Step-by-step explanation:
Kinda complicated to explain, if you need me to then comment and I'll do it
Congruent because you can map the triangles using a reflection across the y-axis which is a rigid motion
