Answer:
{1,2,3}
Step-by-step explanation:
The domain is the set of x's for which the relation exists.
So the x in each pair is actually the first number per pair.
So the domain is {1,2,3} since the set of points is {(1, -3), (2, 4), (3, 7), (3, 6)}.
Two complementary angles make a total of 90, so 3x+6x=90, x=10
Since opposite angles are the same:
angle DEC = 130
We know angle BEC + AED = 360 - 130*2
Since angles in a circle add up to 360 degrees:
BEC + AED = 360 - 260
BEC + AED = 100
This means that BEC = 50 and
AED = 50
Now that we know 2 angles in the triangle CEB we can work out y:
y = 180 - 50 - 70
y = 60 degrees
(0,0) , (1,4) , ( 2,8) are the ordered pairs
