Answer:
360
Step-by-step explanation:
The exterior angles always add up to 360 in a polygon because it's the sum of all the vertexes which would make a circle.
Answer:
z=3 because in the 2(z+3) is like (z+2)+(z+6)
Answer:
A subset is when all of the elements in the subset are in the actual set. A proper subset is a subset which the actual set has at least on more element than the proper subset.
Step-by-step explanation:
For example, Set A, {1,2,3} is a subset of B {1,2,3}. But Set C, {1,2} is a proper subset of B. Set {5,8} is a subset of {2,5,8}.
Answer:
34
Step-by-step explanation:
Points B,C,D, and E are points on the edge of the circle.
and 
are in the same segment.
We have that: 
We want find 
Recall that angles in the same segment are congruent.
So the answer is 34
The first amount would be the original amount as the answer because you are adding and then subtracting the same number. If the increase was 150% then the answer would be 50% more because 150%-100%=50%.
