Answer:
n = 6
Step-by-step explanation:
the formula for interior angle is ( n-2)
but we given the measure of one angle, so solve
720 = (n - 2)180
720/180 = (n - 2)
4 = (n - 2)
combine the like terms
4 + 2 =n
6 = n
Answer:
The answer is 8.88; You look at the number that comes after the second number (the second place after the decimal) and if that number is 5 or above then you round the second number up. (Sorry if it doesn't make sense, but that's the best I can explain it).
Answer:

Step-by-step explanation:
Answer:
The assumption to prove that vertical angles are congruent is "Vertical angles are always congruent".
Step-by-step explanation:
Vertical angles are a pair of angles (not adjacent) opposite each other by a vertex when two lines intersect.
When two lines intercept at a point, 4 angles are formed. Those that are opposite to each other and are not adjacent are vertical angles, these are always congruent.
In this case, we can affirm that if two angles are opposed by the vertex, they are equal.
Have a nice day!
