Answer:
M<FDE = 360 degrees
Step-by-step explanation:
120 degrees is supplementary to x which makes it 120. 120+120=240 degrees. angle x and angle d = 120+120 which makes it 360 degrees.
M<ADE however, is 110+120=280, 360-280=80 degrees which is 110+120+80=360 degrees. So, M<ADE is 360 degrees and it is equal to M<FDE which is also 360 degrees.
All of them are equal. The sum of the figure is 720 Degrees.
Answer:
∠FDE = 130°
Step-by-step explanation:
Since BC and DE are parallel lines, then
∠BDE = ∠ABC = 110° ( corresponding angles are congruent )
The sum of the angles round a point = 360°, thus
∠BDE + ∠BDF + ∠FDE = 360 , hence
110 + 120 + x = 360
230 + x = 360 ( subtract 230 from both sides )
x = 130
Hence x = ∠FDE = 130°
