-- Like every triangle, a right triangle has three interior angles.
-- Unlike any other triangle, one of the angles in a right triangle is a right angle.
The other two are both acute angles.
-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse
-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse
-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
First find the are of the 90 degree triangular end. This is 0.5*a*b where a and b are the two legs of the triangle adjacent to the right angle. Multiply the result by the length of the wedge.

If it's a right angle triangle then use Pythagoras' theorem to find its various lengths.
Measure 3 of any unit on one of the sides that you suppose have a right angle. Measure 4 of the same unit an the oher side you suppose has a right angle. the distance between the marks you made should mbe 5 if it is a right angle
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.
By using Pythagoras' theorem for a right angle triangle.
By using Pythagoras; theorem for a right angle triangle.
If it's a right angle triangle then use Pythagoras' theorem.
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
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.
Use Pythagoras' theorem for a right angle triangle to find the length of the 3rd side.
Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.
if the triangle has one right angle in it
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
Depending on which sides and angle are known you would use one of the trigonometry functions.
You cannot find any angle, or either of the other two sides, in a non-right triangle, when given only one side.
If it's a right angle triangle and you know its base and height then use Pythagoras' theorem to find the length of its hypotenuse.
