If there are two supplementary angles, angle D and angle E, where angle D=(4x+8)° and angle E= (x+17)°, and angle F is a vertical angle with angle D, what is the measure of angle F?
To find the measure of angle F, we need to know the value of x. However, we can determine the relationship between angle D and angle F.
Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. They are always congruent, meaning they have the same measure.
Therefore, angle F has the same measure as angle D.
Since angle D is (4x + 8)°, angle F is also (4x + 8)°.
