Applications of Right Triangles

Video Summary:

Significant Digits Represents the actual measurement. Most values of trigonometric functions and virtually all measurements are approximations. In 1838, Friedrich Bessel determined the distance to a star called 61 Cygni using a parallax method that relied on the measurement of very small angles. You observe parallax when you ride in a car and see a nearby object apparently move backward with respect to more distance objects.
