BAC=ABD. therefore ABD = 20°
BDA = 180° - 20° -20° = 140°
BDC = 180° - 140° = 40°
BCD = 180° - 40° - 20° = 120°
By taking A as our domain and B as our range, we will see that the relation is {(6, 3), (10, 5), (14, 7)}
Here we have:
- A = {6, 10, 14}
- B = {3, 5, 7}
And we want to find the relation:
y = (1/2)*x in AxB.
So, we take values from A, and we input them in the given function, and then we must see if the outcome is in B.
For each value in A we will have:
y = (1/2)*6 = 3
(6, 3)
y = (1/2)*10 = 5
(10, 5)
y = (1/2)*14 = 7
(14, 7)
So we have 3 points that define the relation in AxB:
{(6, 3), (10, 5), (14, 7)}
