You are given two pairs of triangles.
For the first pair of triangles, each angle and side of one triangle is congruent to the
corresponding angle and side of the other. You show that rigid motions can transform
one triangle so that it matches up with the other.
For the second pair of triangles, you show that rigid motions can transform one triangle
so that each side or angle of one triangle matches exactly with a corresponding side or
angle of the other triangle.
What have you proved?

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
