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.
What is the perimeter of a 30 60 90 triangle if the hypotenuse is 3?
The perimeter of a 30-60-90 triangle if the hypotenuse is 3 is: 7.098
What is the sum of side lengths of a triangle?
That number is called the "perimeter" of the triangle.
A triangle has a base of length 20 units and perimeter of 66 units. If a similar triangle has a base of 15 units what is its perimeter?
49.5 units
What is the formula for the perimeter of a equilateral triangle?
Add the lengths of each side together to get the perimeter.
Formula of perimeter of isosceles triangle?
Lengths of: equal side+equal side+base = perimeter
How long perimeter Triangle 4cm side?
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
What is the perimeter of a triangle that has sides 4cm long?
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
How can you find sides of a triangle if one of the side and perimeter is given?
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
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 perimeter for a equilateral triangle with 7.8mm sides?
Perimeter is the sum of the sides. An equilateral triangle has three sides of equal length. So the perimeter in this case would be 7.8mm x 3 = 23.4mm.
What is the perimeter of a triangle that has a area of 6.5 cm?
The minimum perimeter is when the triangle is an equilateral triangle. The perimeter of any other triangle with the same area will be longer. In the case of an equilateral triangle area = (√3)/4 × side² → side = √(4×6.5 cm²/√3) → perimeter = 3 × side = 3 × √(4×6.5 cm²/√3) ≈ 11.62 cm → The triangle has a perimeter greater than or equal to approx 11.62 cm.
Is the perimeter of a triangle equal 180?
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
What is the ratio of the perimeter of the smaller triangle to the perimeter of the lager triangle?
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
What is the perimeter of an equilateral triangle if each side is 40centimeters?
Each side of an equilateral triangle is 9.2 ft, what is the perimeter of the triangle? Solution: 27.6 ft. The perimeter of a triangle is total length of all three sides added up. An equilateral triangle has 3 equal sides. So the perimeter is 9.2×3=27.6 ft.
The perimeter of an equilateral triangle is at most 57 feet. What could be the length of a sides?
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
What do you do to find the perimeter of a triangle?
The perimeter of a triangle is equal to the length of its three sides added together. If you do not know the lengths of the sides, there are many different mathematical techniques for discovering them.
