Answer:
Distance between two crosses:
[tex]1.8966 $ cm[/tex]
Step-by-step explanation:
Each side of the equilateral triangle is 55 cm
Since there are 30 crosses along a side equally distant, the number of gaps between all 30 crosses is 29 (30 -1)
To understand why this is so, imagine there are only 3 crosses separated by equal distances, This means one cross in the vertex, another cross on the opposite vertex and one cross in the middle giving a total of 2 gaps
Therefore the distance between two crosses
[tex]= \dfrac{\text{Side Length}}{\text{Number of gaps}}\\\\\\= \dfrac{55 \;cm}{29}\\\\= 1.8966 $ cm[/tex]
