As you know, eratosthenes endeavored to measure the circumference of the earth. in the process, he determined a certain angle to be about 7.2 degrees. this angle is: (indicate all that are correct - may be more than one choice correct. however, you will lose credit for picking incorrect choices) the tilt angle of the earth's axis with respect to the direction perpendicular to the plane of the earth's orbit around the sun. the angle between an incoming sunray and the ground in alexandria on june 21, summer solstice day. the angle between a long stick he placed on the ground in alexandria and the ground there. the angle between incoming sunrays and the zenith direction in alexandria on june 21, summer solstice day. the angle between incoming sunrays and the vertically pointing stick that he stood on the ground in alexandria on une 21, summer solstice day. question3 at they landing site on a planet, the sky is cloudy, so that at noon on summer solstice day, the landing party cannot see the sun in the planet's sky. however, the following facts are known: the circumference of the planet is 70,000 miles. 600 miles directly to the south of the landing site, at noon on summer solstice day the sun is in the directly overhead direction. from this data, the angle to the sun in the sky at at the landing site at noon on summer solstice day must be (choose the answer closest to the actual value): 3 degrees o 6 degrees 7 degrees. 5 degrees ( o2 degrees
