When the aircraft flies, the flight direction is expressed by the angle between the flight route and the actual South or north direction line. As shown in the figure, the clockwise angle between an (north-south line) and the flight line is used as the flight direction angle. The flight direction angle from a to B is 35 °, the flight direction angle from a to C is 60 ° and the flight direction angle from a to D is 145 °. The angle between AB and AC is multiple Less? What is the angle between AD and AC? And draw the flight line from a with 105 ° angle

When the aircraft flies, the flight direction is expressed by the angle between the flight route and the actual South or north direction line. As shown in the figure, the clockwise angle between an (north-south line) and the flight line is used as the flight direction angle. The flight direction angle from a to B is 35 °, the flight direction angle from a to C is 60 ° and the flight direction angle from a to D is 145 °. The angle between AB and AC is multiple Less? What is the angle between AD and AC? And draw the flight line from a with 105 ° angle

So the angle between AB and AC is ∠ NAC - ∠ nab = 60 ° - 35 ° = 25 ° and the angle between AD and AC is ∠ nad - ∠ NAC = 145 ° - 60 ° = 85 ° flying out of a with a direction angle of 105 °, that is ∠ NAE = 105 °

When the aircraft flies, the flight direction is expressed by the angle between the flight route and the actual South or North line. As shown in the figure, the clockwise angle between an (north-south line) and the flight line is used as the flight direction angle. The flight direction angle from a to B is 38 degrees, the flight direction angle from a to C is 63 degrees, and the flight direction angle from a to D is 148 degrees, What is the angle between AD and AC

Between AB and AC: 63 ° - 38 ° = 25 °
Between AD and AC: 148 ° - 63 ° = 85 °

When an aircraft flies, the direction of the aircraft is expressed by the tutor size between the flight route and the actual north-south direction line,
When the plane flies, the direction of the plane is expressed by the tutor size between the flight route and the actual north-south line. The clockwise angle between an (north-south line) and the flight line is used as the flight azimuth. The flight azimuth from a to B is 35 degrees, the flight azimuth from a to C is 60 degrees, and the flight azimuth from a to D is 145 degrees
Try to find out the angle between AB and AC and the size between AD and AC

According to the meaning of the title, we can see that ∠ nab = 35 °, NAC = 60 °, nad = 145 °
So the angle between AB and AC is ∠ NAC - ∠ nab = 60 ° - 35 ° = 25 °,
The angle between AD and AC is ∠ nad - ∠ NAC = 145 ° - 60 ° = 85 °,
The flight line flying out from a with a direction angle of 105 ° is ∠ NAE = 105 °

As shown in the figure, n represents the North Pole. An aircraft flies from a to B along the meridian. What is the flight direction of the aircraft?
Azimuth of point A: 0,20w
Bearing of point B: 160E

Answer: first due north, then due south
The azimuth of point A: 0,20w, the azimuth of point B: 0160e-n means the North Pole. A plane flies from place a to place B along the meridian, so it flies due north from point a to the North Pole first, and then it flies due south after passing through the North Pole
