The calculated measure of the angle F is 63 degrees
How to determine the measure of the angle F
From the question, we have the following parameters that can be used in our computation:
The quadrilateral EFGH
Also, we have that
EFGH is a parallelogram
This means that the opposite angles are congruent
So, we have
y + 35 = 2y - 47
This gives
y = 35 + 47
y = 82
Next, we have
F = 82 + 35
F = 117
The measure of the angle F is
F = 180 - 117
F = 63
Hence, the measure of the angle F is 63 degrees
