Answer:
- The sum of the eight interior angles not adjacent to these exterior angles is 1280°.
=================
<h2>Given </h2>
- A 15-sided polygon with sum of 7 exterior angles 200°.
<h2>To find </h2>
- The sum of the 8 interior angles, remote to known 7 angles.
<h2>Solution</h2>
<u>We know that:</u>
- sum of all exterior angles of a polygon is 360°.
- sum of each interior and exterior angle pair is 180°.
So the sum of the 8 exterior angles is:
Sum of both interior and exterior angles of 8 angles:
Sum of those 8 interior angles is:
Okay. To find the speed in meters, do 75 * 1,000. because 1,000 meters = 1 kilometer. 75 * 1,000 is 75,000. The speed is 75,000 meters an hour. But, it asks for meters per second and there are 3,600 seconds in one hour. To find this, we have to do division. 75,000/3,600 is 20.8 when rounded to the nearest tenth. The car goes about 20.8 meters per second.
12.3 x 3.1= 38.13 Now go to bed lol
Answer:
120 magazines
Step-by-step explanation:
