In a circle, the degree measure of an arc is the same as the measure of the central angle that intercepts it.
A full circle is 360 degrees.
Add all the measures and set equal to 360 degrees.
One angle measure is not given, but that angle has a mark and another angle has the same mark, so the angle whose measure is not give also measures -9x - 3.
-9x - 3 + x + 107 + (-6x + 8) + (-9x - 3) + (-13x - 1) = 360
-9x - 3 + x + 107 - 6x + 8 - 9x - 3 - 13x - 1 = 360
-36x + 108 = 360
-36x = 252
x = 252/(-36)
x = -7
Answer:
76°
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
52° + 12x + 4 = 22x - 4
52 = 22x - 4 - 12x - 4
52 = 10x - 8 add 8 to both sides
60 = 10x divide both sides by 10
6 = x
The measure of angle F is 12x + 4, replace x with the value we found
m<F 12 × 6 + 4 = 76°
