Answer:
53°
Step-by-step explanation:
i will use ∩ to represent arc since there is no arc sign
if ∩EF = 34, then ∡EFC = 34
think of EFC as an angle in the larger circle
since EFC = 34, ABC = 34 because they are opposite angles and opposite angles are always congruent.
ABD = AB + BD = 19 + 34 = 53
I believe it is the second one
That the answer. will be 0.7 because you put it ib similarly
Answer: The no fewer then sign would be <
Reason: let’s say that Alex wanted no fewer then 5 sheets of paper for a project. Alex can’t finish his assignment with only 4 sheets of paper. He can with 6, 7, 8, 9, etc. how we would label this is like this < 5 sheets. Think of the sign like a monster crocodile. It can eat as much as it can.
Because BA ≅ BC, we know the triangle is isosceles. Because ∠FEC=90°, we know BE is a median and angle bisector of ∠ABC.
Hence ...
... AC = 2×AE = 20 in
... ∠EBC = (1/2)×∠ABC = 65°15'
