Use Pythagoras' theorem of a2+b2 = c2 whereas a and b are the sides of a right angle triangle with c being its hypotenuse or longest side.
the angle is an angle and therefore doesn't have a length. If you want to find the length of the hypotenuse - the leg across from the right angle - it is the square-root of the other two legs each squared.
By using Pythagoras' theorem for a right angle triangle.
a right angle or any other angle does not have a length. your question cannot be answered.
A right angle is always 90 degrees. Another Answer:- If you mean the length of the hypotenuse then use Pythagoras' theorem which is applicable to right angle triangles
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
If it's a right angle triangle then use Pythagoras' theorem.
-- 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 ]
To find the degree of an angle when you know the height and length of a right triangle, you can use the tangent function. The tangent of the angle is equal to the opposite side (height) divided by the adjacent side (length). You can calculate the angle by taking the arctangent (inverse tangent) of the height divided by the length: ( \text{angle} = \tan^{-1}(\frac{\text{height}}{\text{length}}) ). This will give you the angle in degrees.
By using Pythagoras; theorem for a right angle triangle.
In a right angles triangle the sides are named the hypotenuse (the side opposite the right angle) and the other two sides are called the adjacent and the opposite sides. 1) The sine of an angle = length of the opposite side ÷ length of the hypotenuse. 2) The cosine of an angle = length of the adjacent side ÷ length of the hypotenuse. Using 1) The length of the hypotenuse = length of the opposite side ÷ the sine of the angle. Using tables or a calculator obtain the sine of the angle and divide this into the length of the opposite side. The result will be the length of the hypotenuse.
If it's a right angle triangle and an acute angle plus the length of a leg is given then use trigonometry to find the hypotenuse.
