Hair grows at an angle due to the orientation of the hair follicles in the skin. Each follicle is embedded in the dermis at a specific angle, which determines the direction of hair growth. Additionally, the arrangement of the surrounding skin and underlying tissue can influence this angle, resulting in a natural grain or pattern in the hair. This angling can also affect how hair lies and appears when styled or groomed.
Nutri-grain.
Not if eaten with grain products ie bun
Exterior angle is 360/9 ie 40 so interior angle is 180 - 40 ie 140.
90 - 26 ie 64o.
180 - 60 ie 120o
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
90 - 42 ie 48 deg
90 - 42 ie 48o
180 - (360/40) ie 171o
90 - 68 ie 22 degrees
360/9 ie 40 degrees
(90 - 78)/2 ie 6o
