Question

What is the length of ED

Answer 1

Answer:

ED ≈ 2.6 units

Step-by-step explanation:

Using the Sine rule in Δ DEF

$\frac{FD}{sin115}$ = $\frac{ED}{sin20}$

$\frac{6.95}{sin115}$ = $\frac{ED}{sin20}$ ( cross- multiply )

ED sin115° = 6.95 sin20° ( divide both sides by sin115° )

ED = $\frac{6.95sin20}{sin115}$ ≈ 2.6 ( to the nearest tenth )
