Find the area of an equilateral triangle that has a perimeter of 21 inches. round the answer to one decimal?
Area of equilateral triangle: 0.5*7*7*sin(60 degrees) = 21.2 square inches
What is the area of an equilateral triangle that has a perimeter of 36 centimeters Round to the nearest square centimeter.?
Area of equilateral triangle: 0.5*12*12*sin(60 degrees) = 187 square cm
What is the area rounded to the nearest tenth of a square inch of an equilateral triangle that has a perimeter of 24 inches?
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
How do you find the hypotenuse of an equilateral triangle?
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.
How many degrees is one of the angles in an equilateral triangle?
there are 60 degrees in one of the angles in an equilateral triangle
How many distinct equilateral triangles with a perimeter of 60 units have integer side lengths?
There is only one equilateral triangle with a perimeter of 60 units. Its side lengths are integers.
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.
Triangle with a perimeter of 9 and a angle of 60 with a similar triangle with a perimeter of 12 what is the angle degree of the second triangle?
== == The corresponding angle is 60 degrees.
How long are each sides of an equilateral triangle if the perimeter is 60?
20. There are 3 sides to any triangle. For an equilateral triangle all 3 sides are the same length. Therefore for this triangle we can say that, where x equals the length of a side: 3x = 60 x = 60/3 x = 20

What is the formulae fo equalertal triangle?
The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.
What is the area rounded to the nearest tenth of a square inch of an equilateral triangle that has a perimeter of 24 inches?
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
A triangle that measures 60 60 60 degrees is a n?
an equilateral triangle
What is the size of one angle in an equilateral triangle?
Each of the 3 angles in an equilateral triangle are 60 degrees.
Can an equilateral triangle also be abtuse triangle?
No, a triangle can only be equilateral if all of its angles = 60 degrees and 60 degrees is acute, not obtuse.
A triangle with three 60 angles?
That will be an equilateral triangle.
