Question

find angle d,angle f

Answer 1

Answer:

Step-by-step explanation:

taking the ratio of sides  we get that EF/AB =  ED/AC  MEANS TRIANGLES ARE SIMILAR .

          SO RATIO OF ANGLES WOULD BE  SAME

therefore ∠FED/BAC = 15/13       (∠FED = 150 AND ∠BAC = 130   EXPLAINED  IN DIAGRAM)

∴∠D/∠C = 15/13

∠D/20=15/13

SO ANGLE D WILL BE     300/13°

similarly we can find that ∠F = 450/13°
