The length of one side of an equilateral triangle is 11 Find the length of the altitude?
XNathaniel1tw7073
each angle is 60 degrees. If you know trigonometry
sin 60 = Altitude/length of side (from Pythagoras)
A = 9.526 inch
Or, from Pythagoras theorem 5.5 squared + Altitude squared = 11 squared
Altitude = 9.526

The altitude of an equilateral triangle is 8.3m. find the perimeter?
28.75m
The lenght of one side of an equilateral triangle is 10 cm find the altitude of the triangle?
The triangle's altitude is 8.7 (8.66025) cm.
Find the length of the altitude of an equilateral triangle if one side has a length of 6cm?
Side = 6 cm 1/2 of the base = 3 cm Altitude = 3 times square-root of 3 = 5.196 cm (rounded)
How do you find the perpendicular height of a isoceles triangle?
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 - (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you'll have the measure of the altitude.
How do you find the perimeter of a equilateral triangle when a side equals 12yrds?
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
What is the length of the altitude of the equilateral triangle?
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.
The altitude of an equilateral triangle is 8cm . find the side?
The length of each side is 9.2376 cm. (rounded)
How do you find the length of a side of an equilateral triangle when you know the length of the altitude?
Multiply the altitude by [ 2 / sqrt(3) ] to get the length of the side.[ 2 / sqrt(3) ] is about 1.1547 (rounded)
Find the length of an altitude of an equilateral triangle with sides that measure 11.31 m?
9.794747317 m (with the help of Pythagoras' theorem)
The lenght of one side of an equilateral triangle is 10 cm find the altitude of the triangle?
The triangle's altitude is 8.7 (8.66025) cm.
Find The altitude of an equilateral triangle if one of its sides measures 12cm?
Altitude = 10.4 (10.3923) cm
How do you find the height of an equalateral triangle?
To find the altitude or height of an equilateral triangle, take one-half of the length of a side of the triangle and multiple by "square root" of 3. So, if for example, the side has length 10, the height = 5 Square root of 3.
How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
Example problems in right plane triangle?
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
What is the perimeter of an equilateral triangle with an altitude of 15?
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.
Find the length of the altitude of an equilateral triangle if one side has a length of 6cm?
Side = 6 cm 1/2 of the base = 3 cm Altitude = 3 times square-root of 3 = 5.196 cm (rounded)
The perimeter of an equilateral triangle is 32centimeters find the length of an altitude of the triagle to the nearest tenth of a centimeter?
Since an equilateral triangle has three congruent sides (and 3 congruent angles, each of 60⁰), the length of each side is 32/3 cm. If we draw one of the altitudes of the triangle, then a right triangle is formed where the side of a triangle is the hypotenuse, and the altitude is opposite to a 60 degrees angle. So we have, sin 60⁰ = altitude/(32/3 cm) (multiply by 32/3 cm to both sides) (32/3 cm)sin 60⁰ = altitude 9.2 cm = altitude
