If a pair of alternate exterior angles are supplementary, what is the measure of each angle? it should be 180 if im not mistaken
Answer:
x=5/2, y=13/2. (5/2, 13/2).
Step-by-step explanation:
2x+12y=83
5x+3y=32
---------------
2x+12y=83
-4(5x+3y)=-4(32)
---------------------
2x+12y=83
-20x-12y=-128
---------------------
-18x=-45
18x=45
x=45/18
x=5/2
2(5/2)+12y=83
5+12y=83
12y=83-5
12y=78
y=78/12=13/2
3.5 , 7 , 10.5 , 14 , 17.5 , 21 , 24.5 . Because it increases by 3.5 each time
Circumference of a Circle = 2πr
2 π 5
approx 31.41
Area of a Circle πr^2
π5^2
Approx 78.53
