Answer:
DF = 14
Step-by-step explanation:
Andrew was wrong in the assumption that DE = EF
Segments of tangents to a circle from the same external point are congruent
That is
EF = FG = 8
Then
DF = DE + EF = 6 + 8 = 14
Yea they are cuz they have the same side and angle measurements
8 / x^2. 8 is the y variable, and any number squared equals the x variable
For triangles, all angles total 180°
For quadrilaterals, all angles total 360°
Parallelograms have equal opposite angles, so each adjacent pair is 180°
Hexagons are 720°
3. 180 - (90 + 30) = 180 - 120 = 60°
4. 180 - (45 + 45) = 180 - 90 = 90°
5. 360 - (135 + 70 + 93) = 360 - 298 = 62°
6. 180 - 60 = 120°
7. 180 - (120 + 37) = 180 - 157 = 23°
8. Perfect hexagon: 120°
9. Parallelogram: 70°
10. 360 - (90 + 90 + 67) = 360 - 247 = 113°
