Answer:
Perimeter of the final star = 40 cm²
Step-by-step Explanation:
The perimeter of the six-pointed star is the sum of the sides of the 6 equilateral triangles that form a boundary around the star.
1 triangular tiles gas a perimeter of 10cm.
Only 2 out of the 3 equal sides of each of the 6 equilateral triangles form the boundary of the final star.
Therefore, perimeter of the final star = ⅔ of the total perimeter of 6 triangular tiles
= ⅔ of (10*6)
= ⅔*60
= 2*20
Perimeter of the final star = 40 cm²
Step-by-step explanation:
15. 6.06
16. -7.21
17. 1.82
Looking at the diagram, you can tell that y and 116 degrees are supplementary, meaning that they add up to 180 degrees.
therefor 180-116=y
y =64
if we add all the angles we know together, 64 + 72 + 125 = 261
360 - 261 = 99
therefor x = 99
