Given: a convex n-gon
Prove: The sum of the measures of the exterior angles is 360°
Complete the missing parts of the paragraph proof.
For a convex n-gon, interior and exterior angles form
v angles, whose measures sum to 180°.
Because we have an n-gon, the sum of the measures of these linear pairs, one exterior angle at each vertex, is
The sum of the measures of the interior angles is
by the polygon interior angle sum theorem.
To find the measure of the exterior angles, we can subtract the sum of the measures of the interior angles from the
sum of the measures of the linear pairs. Therefore, we have
, which is equal to 360°.

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
