Please provide the steps and answers to questions 9, 10 and 11. equals 180°. This is proved by the Euclidean Geometry I HangleTheorem.ProblemAn airline is mapping routes for its international flights. One route leaves fromRaleigh-Durham International Airport in the United States, travels to HeathrowAirport in London, then to Alexandria International Airport in Egypt, and finallyreturns to Raleigh-Durham. This trip forms a triangular route. Is this triangleEuclidean, spherical, or neither?Spherical; since the path of the airplane is curved, the angles formed will also be curved,and since the earth can be considered a sphere, the triangle is spherical.ExercisesFor each set of three angle measures of a triangle given, does the triangle exist in Euclideangeometry, spherical geometry, or neither?3. 79°, 45°, 45°4. 33°, 87°, 60°6. 21°, 121°, 221°9. 30°, 60°, 90°7. 30°, 40°, 50°10. 70°, 111°, 68°5. 100°, 100°, 100°SG8. 100°, 40°, 40°11. 100°, 80°, 80°12.
