Tenth? It would be 4.8 (5 and up you round up, look at the digit beside the one you are rounding!)
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
the right answer is actually 30,60,90, I got the answer right on the test
