Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?

Ava's altitude is 3 meters.

Step-by-step explanation:

The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.

So that applying the Pythagoras theorem, we have;

= +

= +

25 = 16 +

= 25 - 16

   = 9

x =

   = 3

x = 3 meters

Thus, Ava's altitude is 3 meters.

452,489 to the nearest thousand is 452,000
