well,
sin 26° = EF/4.5
EF = 4.5sin26°
I assume they want you to do long-hand multiplication, or else why would they give you
the approximation for sin 26°. If you are allowed a calculator, why not use the "best" value
of sin 26° that your calculator can give you?
In right triangle DEF, ∠E is a right angle, m∠D=26∘, and DF=4.5.
sin26∘≈0.44
cos26∘≈0.90
tan26∘≈0.49
What is the measurement of EF
