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

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.
