Answer:
EF ≈ 3.8
Step-by-step explanation:
Using the Sine rule in Δ DEF
=
, that is
=
( cross- multiply )
EF × sin50° = 3 × sin75° ( divide both sides by sin50° )
EF =
≈ 3.8
If '1' is 34 '3' is 34 too.(opposite angles). If '3' is 34 '5' is so too.(It's a rule, taught us as 'Z rule') If '5' is 34 '7' is so too(opposite angles again).
Well the answer is 34.
