Andrew is at point A in a park. A deer is three KM directly north of Andrew. At pointy D. Brian is 1.8 KM due west of Andrew, at point B. Calculate distance between Brian and the deer

Respuesta :

Answer:

Distance between Brian and deer is 3.5 km.

Step-by-step explanation:

From the figure attached,

Andrew is at a point A. A deer is at point D which 3 km North of Andrew.

Brian is at point B, 1.8 km west of Andrew.

Now from right angle triangle ABD, we apply Pythagoras theorem.

BD² = AB² + AD²

BD² = 3² + (1.8)²

BD² = 9 + 3.24

BD = √12.24

BD= 3.498 ≈ 3.50 km

Therefore, distance between Brian and deer is 3.5 km.
