Answer:
7
Step-by-step explanation:
Let's say our sum is s.
s = 10 right angles
a right angle is 90 degrees
s = 10 (90)
s= 900
Given the amount of sides in a polygon (n), the sum of the interior angles is equal to
(n-2) * 180
Therefore, the sum of the interior angles is equal to
(n-2) * 180 = 900
divide both sides by 180 to help isolate n
n-2 = 5
add 2 to both sides to isolate n
n = 7
Since we're starting with a negative we're going to disregard the negative sign and add the numbers together: $10.28 + $39.89 = $50.17. :)
Answer:
3:42
Step-by-step explanation:
Add 57 minutes to 2:45
2:45
57
--------------
2:102
but there are 60 minutes in 1 hours so subtract 60 minutes and add 1 hour
2: 102
+1 -60
------------
3:42
You will end at 3:42
