The sum of the interior angles of a quadrilateral is _______. 180° 90° 270° 360°
2 answers:
Answer:
360°
Explanation:
Quadrilateral are polygons that have four sides. The sum of internal angle of a quadrilateral is 360°. The quadrilateral are closed shape with four sides. Examples of quadrilaterals are trapezium, rectangle, square, Rhombus and parallelograms.
Every quadrilaterals can be divided into two triangle. The sum of angle in a triangle is 180°. Adding the two triangle angle together , we will get the sum as 360°.
Sum of the interior angle of a polygon = 180(n-2) . In the case of quadrilateral, it has 4 sides. n represents the number of sides of the polygon .
interior angle of a quadrilateral = 180(4-2) = 360°
The image illustrate how the interior angle of quadrilaterals can be sum.

Answer:
a) v = 19,149.6 m/s
b) f = 95%
c) t = 346.5min
Explanation:
First put all values in metric units:
The equation of motion you need is:
where is the final velocity, a is acceleration and t is time in hours.
Since the spaceship starts from 0 velocity:
Next, you need to calculate the distances traveled on each interval, considering that both starting and final intervals travel the same distance because the acceleration and time are equal. For this part you need the next motion equation:
solving for first and last interval:
Since the spaceship starts and finish with 0 velocity:
Then the ship traveled at constant speed, which means that it traveled:
Which in percentage is 95% of the trip.
to calculate total time you need to calculate the time used during constant speed:
That added to the other interval times:
