You use the law of Pythagoras: a2 + b2 = c2, where a and be are the sides adjacent to the right angle, and c is the side opposite. Replace the two sides that you know, and solve for the third one.
Pythagoras: hypotenuse squared = sum of squares of other two sides.
If you know two of the sides you can calculate the third as above.

What right triangle has legs of equal length?
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
How can you find a missing side or angle of a right triangle?
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
In a right triangle the sine of any angle is?
The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.
How do you find the angle of a right triangle with the length of two legs?
-- 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 ]
What is the name of A triangle with sides of no equal length?
A triangle with no right angle and sides of different lengths is a scalene triangle.
What do you do in trigonometry?
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
How do you find the length to a missing side of a right triangle?
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.
How do you use sine in math?
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.
How long must a right triangle be?
It can be any length; a right angle triangle just needs to include a right angle somewhere. But length has nothing to do with whether it is a right angle or not.
What is the formula to find the length of a right angle triangle?
By using Pythagoras' theorem for a right angle triangle.
What is the missing side of the right triangle called?
The missing side of a right triangle is called the hypotenuse. This side is opposite the right angle and is the longest side of the triangle.
What is a right scalent triangle?
A right scalent triangle is a triangle with a right angle and no sides equal in length.
What right triangle has legs of equal length?
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
A triangle with 2 equal sides but no right angle?
a triangle with two sides the same length and no right angle
What is the measuremeant of missing angle that's 90 and 32 degrees?
If that's a right angle triangle then the missing angle is 58 degrees
What triangle has all sides the same length and has a right angle?
equilateral right triangle
What does right isosceles mean?
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
