➜︎Question
Describe what you notice when you create the inverse ratio.
- How do you describe it?
- What do you notice?
- How do you create it?
➜︎Answer
A function composed with its inverse function yields the original starting value. Think of them as "undoing" one another and leaving you right where you started. Basically speaking, the process of finding an inverse is simply the swapping of the x and y coordinates.
- You can describe a inverse ratio by saying how it works
- You can notice the difference
- You could possibly know
Sid wrapped 8 gifts.
Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.
Solution:
As per the problem we have
Angle A and angle B are supplementary angles.
As we know that , two angles are supplementary angles if their sum is 180.
So when these two angles will be together on a plane will make a straight line.
Hence , when Angle A and angle B are supplementary angles.
Then
The sum of the angles is 180 degree.
