Hi !
I’m sorry I won’t be doing the solving for you because it should be easy but I will give you the logic in case you don’t know how to solve them...
Please look at the picture below
According to the theorem we know that DE is:
DE = 1/2 ( BC)
Solve for X then find the values.
Note: remember that if you want to make your life easy multiply both side by 2 to get rid of the 1/2.
