180 degrees - 116 degrees =64 degrees (angle PDC)
180 degrees - 64 degrees = 116 degrees (angle APD)
This may help:There are

gallons of lemonade.
Two friends share the lemonade.
What fraction of the lemonade does each friend receive?
To solve you do kcf or keep change flip.
You keep

and change division to multiplication.
Then

is changed to

<span>The answer would be </span>

Hope That Helps!
There will have to be 5 because of the 4
Y'sinx=ylny, is equivalent to <span>dy / dx (sinx=ylny, and </span><span>dy sinx=ylny dx
it is similar to dy/</span>ylny = dx/sinx
so integral (dy/ylny = integral dx/sinx)
integral dx/sinx)= Ln{abs value ( tan(x /2 + pi /4)}
integral (dy/ylny= ln(lny)
final answer is lny = {abs value ( tan(x /2 + pi /4)}+C, you can find y, or x
