Answer 2

Answer:

The parallax angle is the angle between the Earth at one time of year, and the Earth six months later, as measured from a nearby star. Astronomers use this angle to find the distance from the Earth to that star

the astronomers use a method similar to the one you used with your homemade quadrant. Twice the distance to the Sun, divided by the distance to the star (which is unknown so far) is equal to the tangent of the parallax angle of the star.

tan (angle) = 2 AU/ distance

or

distance = 2 AU/ tan (angle)

(1 AU is the distance from the Earth to the Sun)
