Answer:
Both angles B and C are equal to 40°
Step-by-step explanation:
The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.
Now we are going to plug x back into each expression to solve for angles B and C.
Angle B
⇒
Angle C
⇒
Both angles B and C are equal to 40°
Answer:
They are inverse functions
Step-by-step explanation:
A property of inverse functions is that if
We can plug in x = 3
That means that, supposing they are inverse functions, g(7) should equal 3
It checks out
Another way to see if two functions are inverse is to swap the x and y of one of the functions.
ex.
Since, after the swap, the functions are equal, we know it is an inverse function
