It depends on what information you do have about the triangle. There are different equations depending on whether you know the lengths of three sides, the lengths of two sides and the measure of the included angle, the length of one side and the perpendicular distance to the other vertex (base and height).
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
the sides can be found out by using trignometry.. sines and cosines.. sine of an agle is perpendicular/hypotenuse cosine of an angle is base/hypotenuse..

If you also know its shadow then you can work out the angle of elevation

You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
There is not enough information to calculate an angle. At the very least, you need to know that the polygon is regular. You do not know that.
In order for your to know the weight must know the thickness of the angle bar.
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
You would need to know other physical properties to be able to calculate the length. As you would need to know certain properties to be able to calculate the volume, for instance.
You need to know at least one side......after that you can use the angles to apply the equations, SOH CAH TOA.
