Answer:

a) 36°

b ) 18°

Step-by-step explanation:

The formula is given as:

The measure of each exterior angle =360°/n, where n = number of sides of a polygon.

a) decagon

Decagon = 10 sides

Hence, the measure of each exterior angle = 360°/10

= 36°

b) 20-gon

20-gon = 20 sides

Hence, the measure of each exterior angle = 360°/20

= 18°

Anna walks at a constant rate of 8 miles every 2 hours Graph a line to show the relationship between the time in hours, 1 and th
stiks02 [169]

Answer:

We see that the only complete time-distance pair indicates that she walked 6.4 miles in 2 hours. If she walked at a constant speed, we can conclude that girl walked 3.2 miles in 1 hour. Using this speed, we can find the remaining values in the table. The easier entry to complete is finding out how far she walked in 5 hours: 5 hours⋅3.2 miles/hour=16 miles. To find out how long it took to walk 8 hours we can either notice that 8 is half of 16, so it took half the time to walk half the distance or we can divide 8 miles by 3.2 miles per hour to find that it took 2.5 hours
