Find the sum of the interior angles of a quadrilateral with 15 sides?

2340°

Step-by-step explanation:

To find the sum of interior angles of any shape, use the formula: 180(n - 2), where n is how many sides there are. So,

180(15 - 2)

180(13)

2340

2,340

Step-by-step explanation:

Using Formula

=>

Where n is the number of sides. Here, no. of sides is 15

=>

=>

=> 2,340

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
