The 3 sides of an equilateral triangle are all equal in length and its 3 interior angles are equal in size each measuring 60 degrees
You can't calculate any angle if all you know is one side of the triangle.
The sides of the triangle measure 3 feet, 4 feet, and 5 feet. 5 feet is the longest side.

We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.
The measure of a triangle's angles if the hypotenuse is six and one side is one are:9.594 degrees80.41 degrees90 degrees
No, but if associated with some measurement units, it can be the measure of one side of a triangle.
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
the Pythagorean theory
The measure of the hypotenuse of a right triangle if one side is 24 inches and other side is 30 inches is: 38.42 inches.
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
It depends on whether X is the missing side, one of the angles or some other measure of the triangle.

Measure them
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.
You can't calculate any angle if all you know is one side of the triangle.
