Mathematics
1 answer:
STALIN [3.7K]3 years ago
4 0

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 )
