2. An astronomer observes a distant star on two dates six months 90°00'00" and the other is 89°59'58.7". If the distance from the
apart forming a right triangle as shown. One angle is exactly
earth to the sun is 93 million mi then find the distance to the
star (side marked "leg").

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
