Answer:
3.6° = ext. angle
Step-by-step explanation:
For the shape to be a regular polygon, all interior angles must be congruent.
We can find every interior angle by using the formula:
176.4 = each int. angle
We also know that int. and ext. angles are supplementary!
180 = 176.4 - x
3.6° = ext. angle
To solve this problem,you need to use the formula d = rd (distance = rates x time)She runs at a speed of 7 mph and walks at a speed of 3 mph. Her distance running is d = 7trwhere tr is the time she spends running Her distance walking isd = 3twwhere tw is the time she spends walking The distances are the same so7tr = 3tw We also know that the total time is 4 hourstr + tw = 4tr = 4-tw Substitute this value of tr in the first equation7tr = 3tw7(4-tw) = 3tw28-7tw = 3tw28 = 10tw2.8 = tw Denise will spend 2.8 hours (2 hours, 48 minutes) walking back and 1.2 hours (1 hour, 12 minutes running.

Answer:
16
Step-by-step explanation:
Given that:
Length of two sides of the triangle = 1 and 16 ;
The largest possible whole-number length of the third side would be ;
Recall from triangle inequality theorem; the length of any two sides of a triangle is greater than the third side. Therefore. The largest possible whole number value the third side could have is:
Assume the third side is the largest :
Then, the third side must be less than the sum of the other two sides ;
Third side < (16 + 1)
Third side < 17
Therefore, the closest whole number lesser than the sum of the other two sides is (17 - 1) = 16
Answer: $4.50
Step-by-step explanation: If it is 50% off then you take the price of $2.25 and double it. So 2 times $2.25 which is $4.50.
A would equal negative 60
