Problem 4
x = interior angle
y = exterior angle
x = 3y since "each interior angle...is three times the measure of each exterior angle"
The interior and exterior angles are supplementary, meaning,
x+y = 180
3y+y = 180
4y = 180
y = 180/4
y = 45
So we know that
n = 360/y
n = 360/45
n = 8
You are correct in saying that this is an octagon
===========================================================================================
Problem 5
x = measure of missing angles
Find the sum of the interior angles
S = 180*(n-2)
S = 180*(5-2)
S = 540
The five interior angles add up to 540 degrees
Add up the five angles, set equal to 540, then solve for x
90+90+90+x+x = 540
2x+270 = 540
2x+270-270 = 540-270
2x = 270
2x/2 = 270/2
x = 135
So you have the correct answer of choice C) 135 degrees
===========================================================================================
Problem 6
S = 180*(n-2)
S = 180*(6-2)
S = 180*4
S = 720
You have the correct answer. Nice work on all three correct answers.
Answer: 4*4^2= 64
text me on brainly fo the other answer i don't have time
Step-by-step explanation:
The answer will be 7.50 because you are doing your times if you do divid its going to be hard so times to get your answer.

Answer:
50men working in 5days will lay 100 meters
Step-by-step explanation:
If 20men working for 10days lays 500meters
then, 1 man will lay 10,000 meters in 10 days
also, 1 man will lay 1000 meters in 1 day
If 1 man lays 1000 meters in 1 day,
Then, 50 men will lay (1000 meters / 50 ); 20 meters in 1 day
also, the same 50 men will lay (20 meters x 5days); 100 meters in 5 days.
Therefore, 50men working in 5days will lay 100 meters
