How do you find the value of x in a triangle?
Solving for X in a Right Triangle Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
What is the length of one side of an equilateral triangle?
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°….

What is the side length of an equilateral triangle?
An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees.
What is sum of triangle?
The sum of the three angles of any triangle is equal to 180 degrees.
What is the angle between two sides in an equilateral side?
In an equilateral triangle all the sides are equal and all the angles are 60°. In an isosceles triangle two sides are the same length and two angles (the angles formed with the base line) are equal.
How many sides does an equilateral triangle have?

How to calculate the area of an equilateral triangle?
1. Given the side find the perimeter, semiperimeter, area and altitude 2. Given the perimeter find the side, semiperimeter, area and altitude 3. Given the semiperimeter find the side, perimeter, area and altitude 4. Given the area find the side, perimeter, semiperimeter and altitude 5.
How to find the length of the side of an equilateral?
The area of an equilateral triangle is , what is the length of each side? An equilateral triangle can be broken down into 2 30-60-90 right triangles (see image). The length of a side (the base) is 2x while the length of the height is .
How to find the length of the side of a triangle?
The smallest side in the given figure is the base, the second longest side is the height, and the longest side is the side of the triangle itself. Thus, we can use the ratio and the length of the height to set up the following equation: Plug in the given height to find the length of the side.
Which is a special case of an equilateral triangle?
An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. The altitude shown h is h b or, the altitude of b. For equilateral triangles h = ha = hb = hc. If you have any 1 known you can find the other 4 unknowns.
