< x is 90 degrees because triangle ABC is isosceles and AD bisects < BAC.
Triangle BAD is right angled so < y = 90 - <ABD
<ABD = <ACD ( because triangle ABC is isosceles
So < ABD = 47 degrees
Finally y = 90 - 47 = 43 degrees answer
Answer:
its c because the x is not repeating so let's say x are people and y is the are the location. multiple x values can give the the same y but an x value can only give one y if x give more than one y value, or in other words repeats itself, then is not a function
The first choice does NOT represent a function
Step-by-step explanation:
the x vaules in the first two ordered pairs (2), each have a different y value which makes it nonfunctional :)
