Right angles are always 90 degrees, (or pi/2 radians if you're into such things) so there isnt really anything to calculate.
You can check that a triangle contains a right angle by verifying it obeys pythagoras theorem,
x2 + y2 = h2 where x and y are the lengths of the two other sides and h is the length of the longest side (the hypotenuse).
If this is the case, the right angle is the one opposite that side, if not, the triangle doesn't contain a right angle.
If you're only given the base, then you can't calculate the other leg. If you have any one of the following, then you can calculate all of the parts of the triangle: -- length of the other leg -- length of the hypotenuse -- size of either acute angle

You can use the cosine rule to calculate the central angle.
Length will equal the volume divided by the other two numbers.
length times with times height
Height will be h=base*tan(angle).

You can use the cosine rule to calculate the central angle.
the length is: 2rsin(1/2 theta) where r is the radius and theta is the included angle.
By using the tangent ratio of: opposite/tangent angle = adjacent which is the base
Length will equal the volume divided by the other two numbers.
length times with times height
The answer depends on whether the base is one of the legs of the right angle or the hypotenuse. Also, a triangle cannot have a diagonal.
Please clarify what data is given, and what you want to solve for. To calculate the perimeter, add the length of all four sides. To calculate the area, the formula is basically same as for a rectangle: length x height; however, the height must be measured perpendicular to the side which you use as "length".
you need to know the formula the arc length is equal to the radius times the angle made by the length of arc s = r(theta) s=arc length r=radius theta=angle
To calculate the width of a box, or cube, you need to use the following formula: W = (V) / (LxH) given that (V= volume, L= length, W= width, H= height) and volume, height and length measurements are already given.
