Alltså helt freakin' underbart. Hade matteprov idag, och en av uppgifterna kan du läsa nedan;

U4) An army of orcs are planning a raid on the Elven city of Rivendell. To succeed they must climb a steep mountain wall. From a distance the orcs measure the angles in the figure below, hoping to figure out how high the mountain wall is. They fail miserably, however, and the elves never even know the arcs are there.

So, are you smarter than the average orc? How high is the mountain wall? :)



Oh jesus och alla hans kompisar.
