A stick 2m long is placed vertically at point b .The top of the stick in the ls in line with the top of a tree as seen from point a .Which is 3m from a stick and 30 m from the tree how tall is the tree

20 Metres

Step-by-step explanation:

I have prepared the diagram below for reference

Let |BC| be the length of the stick and |DE| the length of the tree.

We use the idea of similar traingles,

|BC|=2m, |AB|=3m AND |AE|=30m

We cross multiply

|DE| X 3 = 2 X 30

Therefore, the height of the tree is 20 metres

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
