Use the formula for the area of a circular sector, and solve for the angle.For a circular sector: area = radius squared times angle / 2 (Note: The angle is supposed to be expressed in radians; and in this specific problem, there is no need to convert it to degrees.) Since you know the area and the radius (according to the comments added to this question), you can solve for the angle. Once you know the angle (in radians!), the arc length is simply angle x radius.
The answer will depend on what x is: another angle, or length of side or median or whatever. Since you cannot be bothered to provide that information, I cannot provide a sensible answer.
The answer depends on what the question is and what other information you are given.
I'd really need to see a sketch of the problem. Your description leavestoo many fuzzy details.I'm not sure what 'split in 2' means.'20cm' can't be the measure of an angle.I don't know what part of the triangle 'x' is.There must be a length given for something.
You can't. To calculate another side length you need an angle. you need either two angles and a side length, or two side lengths and an angle to solve for other angles or side lengths. No matter what the case, you need three pieces of information i do not understnd it
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area

you must have at least 2 given sides or a given angle you can use the pythagorean theorem formula c² = a² + b² try the link below for a computation
The answer depends on what the question is and what other information you are given.
No. You need either another angle or the length of another side. For example, to solve a2 +b2=c2 (the formula for a right triangle, in which c is the hypotenuse) you must have values for 2 variables to solve for the third.
It depends on the details of the specific triangle.
You cannot without knowing what the shape is.

To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
You cannot solve for a leg in any triangle without at least one other side.
