Function or not a function¿

it is a function

Step-by-step explanation:

You just have to do y2-y1/x2-x1 and if you do everything for the first time you get 6/12 which is 2 and for the second one you get 6/12 which is 2 so it is a function

Hey there!!

We know that the angles 7 and 8 are supplementary.

Hence,

... angle7 + angle8 = 180

We know angle7 is 92.

Hence,

... 92 + angle2 = 180

... angle2 = 180 - 92

... angle 2 = 88

Hence, the answer is 88°

Hope my answer helps!
