C) 94 degree's
All triangles add up to 180 degree's
180 - ( 52+34) = 94

Answer:
∠ ABC = 81° , ∠ FEC = 90°
Step-by-step explanation:
Since AB ≅ BC then Δ ABC is isosceles.
The median BE is therefore
The angle bisector of ∠ ABC and
BE bisects AC at right angles.
Thus
∠ ABE = ∠ CBE = 40° 30' , then
∠ ABC = 2 × 40° 30' = 81°
Since BE is perpendicular to AC then
∠ FEC = 90°
Symmetry is when an image or being is halved into two, and both sides are the exact same to each other.
Answer:
The mean or average is 9.5 for this set of data. The median is 10.5 and the range is 5.
