Answer:
The sum of the interior angles of a quadrilateral <u>equals</u><u> </u> the sum of its exterior angles.
Step-by-step explanation:
The sum of the exterior angles of a quadrilateral is 360 degrees.
The sum of the interior angles = (n-2)*180
Here n = 4, the number of sides.
Quadrilateral has 4 sides.
The sum of the interior angles = (4 - 2)*180
= 2*180
= 360 degrees.
Therefore, the sum of the interior angles of a quadrilateral <u>equals </u> the sum of its exterior angles.
Hope this will helpful.
Thank you.

Answer: The person's speed is 8 miles per hour.
Step-by-step explanation:
To solve we want to convert the 
and 
proportionally for the number of miles per hour. We know that multiplying a fraction by its reciprocal will equal 1. So let's do that for the value of the hour.
×
Since we multiplied that to the number of hours we must also do that for the number of miles.
