Equilateral triangle is a triangle in which all its sides are equal.
Given:
side = 10 cm
Area of an equilateral triangle = √3/4 a²
1st: a = 10 ; A = 43.3 cm²
2nd: a = 5 ; A = 10.83 cm²
3rd: a = 2.5 ; A = 2.71 cm²
4th: a = 1.25 ; A = 0.68 cm²
5th: a = 0.625 ; A = 0.17 cm²
6th: a = 0.3125; A = 0.042 cm²
7th: a = 0.15625; A = 0.011.cm²
Summation: a1/1 -r ; a1 = 43.30 ; r = 0.25
43.30 / 1 - 0.25 = 43.30/0.75 = 57.73 cm²
The sum of the areas of the triangles if the process is continued without end is 57.73 cm²
Answer:
3,600
Step-by-step explanation:
Volume of a triangular pyramid is V=1/3 Base times height.
B=1/2bh
B=1/2 (24)(30)
B=360
The height is 30 so we now multiply 30 times 360 which is 10,800.
Last, we multiply 10,800 times 1/3 which is <u>3,600.</u>
Hi,
<em>If we sum the measurement of all angles, we should find 360°</em>
<em>Because 360° corresponds to a complete revolution.
</em>
360 - 108 - 81 - 59 = 112°
x = 112°
