Answer:
x = 41°
∠1 = 123°
∠2 = 57°
Step-by-step explanation:
If angles 1 & 2 are supplementary, that means...
To find the value of each angle, you first must find the value of x by plugging in the values of both angles...
First, combine like values, then subtract add 25 to both sides.
Then, divide both sides by 5, and plug the value of x into the original equations for angles 1 & 2.
Answer:
Step-by-step explanation:
Call
Now,
This is the inverse of the given function.
You can cross - verify it by substituting a point, say,
We see that the point satisfies both the equations.
