Question

PLEASE HELP!!!!! Geometry

Answer 1

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
