Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
Each side of the triangle is 16.16581 units in length.
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
The answer is butt head ha ha ha suckers
Height = sqrt(3)/2 * length of side So here, approx 4.3301 cm
The triangle's altitude is 8.7 (8.66025) cm.
The altitude of an equilateral triangle is (√3)/2*a. where 'a' is the side of the triangle. It can be just find by giving a perpendicular to the base of the triangle, the base of the triangle become a/2 and one side is a. so by applying Pythagoras theorem we will get the desired formula.
Given an altitude of 12 units, an equilateral triangle has side lengths of 13.9 (13.85641) units.
No. The altitude is smaller.
Here are a couple Find the altitude of a triangle with base 3 and hypotenuse 5. Find the altitude of an equilateral triangle with each side to 2
Each side of the triangle is 16.16581 units in length.
Multiply the altitude by [ 2 / sqrt(3) ] to get the length of the side.[ 2 / sqrt(3) ] is about 1.1547 (rounded)
There is not enough information to answer the question.
Given side lengths of 14 units, the altitude is 12.1 (12.12436) units.
Given side lengths of 8 units, an equilateral triangle will have an altitude of 7 (6.9282) units.
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
With an altitude of 10 units, this triangle's sides each measure 11.55 (11.54701) units.
