Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides

Answer:
x = 77 degrees
Step-by-step explanation:
To get the value of x, we use the angle arc relationship
Mathematically, we have this as follows;
x = (76 + 78)/2
x = 77
Answer:
y=36+5x
Step-by-step explanation:
5x -y = -36
-5x -5x
-y= -36 -5x
divide the entire equation by -1 to get rid of the negative on the y and you get the answer above!
