Geometry answers to a plane travels?
Seems to have vanished somewhere on course? Need more details which can be added in the details box just below the question box.
A plane travels from Des Moines to Phoenix, on to Atlanta, and then completes the trip directly back to Des Moines. Write the lengths of the legs of the trip (because it forms a triangle) in order from greatest to least. The angle degrees are.. Des Moines: (8x + 4) Phoenix: (11x - 37) Atlanta: (5x + 21) The longest legs are opposite the largest angles. The sum of the angles is 180°, so we have 8x + 4 + 11 x - 37 + 5x + 21 = 180° 24 x - 12 = 180° divide by 12 2 x - 1 = 15 2x = 16 x = 8 Angle D = 68° Angle P = 51° Angle A = 61° So the legs in order from longest to shortest are: Phoenix to Atlanta Des Moines to Phoenix Atlanta to Des Moines
Give more context and details. I don't know enough info for the answer
