I need help please for geometry

mart [117]

Answer:

EF ≈ 1.98

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26° = $\frac{opposite}{hypotenuse}$ = $\frac{EF}{FD}$ = $\frac{EF}{4.5 }$ ( multiply both sides by 4.5 )

4.5 × sin26° = EF

4.5 × 0.44 = EF , that is

EF ≈ 1.98 ( to 2 dec. places )
