The Pyraminx is a Rubik's cube-type toy in the shape of a triangle-based pyramid. Every edge of the Pyraminx below is 15\,\text{cm}15cm15, start text, c, m, end text long. The pyramid's height is h=12.2\,\text{cm}h=12.2cmh, equals, 12, point, 2, start text, c, m, end text. The triangle drawn with dashed lines is a right triangle.

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.

the two may have that, even a breakdown is probably offered
