The calculated measure of the angle JED is 51 degrees.
How to determine the measure of the angle JED
from the question, we have the following parameters that can be used in our computation:
angle FED = 51 degrees
If angle FED = 51 degrees, then angle JED must also be 51 degrees.
This is because angle JED is the vertical angle corresponding to angle FED.
vertical angles are congruent angles
So, we have
JED = 51 degrees.
Hence, the measure of the angle JED is 51 degrees.
