First assignment - Brigita and Jurgita

Method 1

*Jurgita's height - 1,73  m
 * Jurgita stood up to the tree,and then Brgita stood next to a tree. Brigita tried to see, how many times, the tree was bigger. Tree  was bigger 4.5 times.
* 1,73*4.5=7,9 m
* This task was easy to perform. It took not much time.

Method 2

The teacher gave us a great ruler, which measured a Brigita's hand. It was 60cm.Brigita's stood next to the tree, and then started walking backwards until the stick was the same size as a tree. She stopped then when the ruler was as tall as tree was.The distance between Brigita's feet and the tree was 8.1m.
In the end we used the similar triangles' properties to calculate the tree's height. The answer was 8.1 m.
The task was not easy to make, but we did it!

Method 3

We weren't able to do it because the weather was very grainy.
