Answer
Triangle = 60° ; Quadrilateral = 90° ; Pentagon = 108° ; Octagon = 135° ;
Decagon = 144° ; 30 -gon = 168° ; 50 -gon = 172.8° ; 100 -gon =176.4°
Step-by-step explanation:
You follow the equation (N-2)*180, then divide the answer with the the number of sides. Example for Triangle: (N-2)*180=(3-2)*180=(1)*180=180 then divide by 3 because in a triangle there are 3 sides. 180/3=60.
Multiple what you have already: 36x25 = 900
Subtract that from how much you need to earn:
1620-900=720
Divide how much more money you need by how much money each car is:
720/36= 20
You need 20 more cars
X= 180 - 157
= 23
Therefore, X is 23 degrees. A straight line has an angle of 180 degrees, so subtracting the given angle would give you X.
Answer: A
Step-by-step explanation:
If you put 0 in for x, then you would be dividing by 0. Dividing by 0 is always undefined.
