Answer:
Angle B is 41 degrees
Step-by-step explanation:
1) find the supplement of the 113 degree angle; it is 180-113, or 67, degrees.
2) recognizing that the sum of the interior angles of a triangle is 180 degrees, add up 67 and 72 degrees, obtaining 139 degrees, and subtract this sum from 180 degrees:
180 degrees - 139 degrees = 41 degrees (answer)
The steps are outlined above; the end result is that <B is 41 degrees.
We have a function,

and we are asked to find its inverse function.
An inverse function essentially gets you the original value that was dropped into a function.
For example,
If I put 5 into
I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.
The way to determine the inverse function swap the x and the
, then solve for
,



Of course the notation demands that the obtained function be called,

Hope this helps :)
Answer:
5+-8=0
Step-by-step explanation:
Its really easy, first, it says sum, so that means add it and then it said opposite. The opposite of -8 is 8, so put it all together and its 8+-8=0
