Bessel's star (61 cygni) was the first star whose distance was calculated using the parallex method. the star is known to make an angle of 570 milliarcseconds between two opposite points of the earth's orbit. how would you use this information to calculate the distance to the star. write the formula below.

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
