So, for something to be a function see that we want one x value to correspond to only one y value. Solving for y here gives us:
So we see that for every x, there are actually two y values output, so it is not a function.
Answer:
60, 45, 75.
Step-by-step explanation:
A triangle must be; when you add up all its angles the number is 180.
Ex: Angle 1+Angle 2+Angle 3 = 180
-
First, let's try 60,40,70.
60+40+70 = 170, which isn't 180.
Next...
60+45+75 = 180, so that is the answer.
If you still want to try the third one...
60+45+80 = 185
The answer is 32 because the angle FHG is 120 and angle FGH is 28. Add those two together and you get 148. Then you subtract that from 180 and the answer is 32.
