Mathematics
1 answer:
Svetlanka [38]3 years ago

Answer:

2 km

Step-by-step explanation:

Reference angle = 45°

Opposite = u

Hypotenuse = 2√2 km

To find u, apply SOH:

Sin 45° = Opp/Hyp

Sin 45° = u/2√2

√2/2 = u/2√2 (sin 45 = √2/2)

Cross multiply

2*u = √2*2√2

2u = 4

Divide both sides by 2

u = 4/2

u = 2 km
