Use Pythagoras' theorem:
52-22 = 21 and the square root of this is 4.582575695 or about 4.6 units in length

In a right triangle the square of the length of the hypotenuse is equal to the?
pythagorean theorem is a2 + b2 = c2 (only in right triangles) c is the length of the hypotenuse, and a and b are the lengths of the other two legs.
The length of one leg of a right triangle is 10ft and the length of the hypotenuse is 2 ft longer than the other leg What is the length of the hypotenuse and the other leg?
If the other leg has length X. Knowing the rule for triangles a^2+b^2=c^2 and that hypotenuse is x+2 10^2 + X^2 = (X+2)^2 you can solve to find X = 24 and the hypotenuse is 26.
Are some right triangles are also equilateral triangles?
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
What length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse is 10 feet long.?
Using Pythagoras' theorem for right angle triangles then the other leg is 6 feet long
Is hypotenuse only for right triangles?
yes
In a right triangle the square of the length of the hypotenuse is equal to the?
pythagorean theorem is a2 + b2 = c2 (only in right triangles) c is the length of the hypotenuse, and a and b are the lengths of the other two legs.
What is the hypotenuse leg theorem?
If two right triangles have (hypotenuse and a leg of one) = (hypotenuse and the corresponding leg of the other) then the triangles are congruent.
What is the hypotenuse leg therom?
If two right triangles have the hypotenuse and leg of one equal respectively to the hypotenuse and leg of the other, then the triangles are congruent.
What is a cosine?
In trigonometry, when we look at right triangles, the cosine is the ratio of the length of the adjacent side to the length of the hypotenuse.
A right triangle has leg lengths 5 and 12 the length of the triangles hypotenuse h is?
Using Pythagoras' theorem the length of the hypotenuse is 13 units
How do you find the length of the sides of a right triangle given the hypotenuse?
You can't. You need some more information. If you only know the length of the hypotenuse, you can draw an infinite number of different right triangles that all have the same hypotenuse.
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
Does the Pythagorean Theorem work on all triangles?
No, the pythagorean theorem only works on right triangles, but it will work on any right triangle. This is because the Pythagorean Theorem states that length of Leg A squared plus the length of Leg B Squared equals the length of the hypotenuse squared. A hypotenuse is always found opposite a right angle. Only right triangles have right angles; therefore, the Pythagorean Theorem only applies to right triangles. :D
How do you find the hypotenuse when only one length is given?
If the only information you have is the length of one side of a triangle, there are an infinite number of triangles having that length. Since the hypotenuse is defined to be "The side opposite the right angle in a plane right triangle", you will need the length of the other side to find the hypotenuse using the Pythagorean theorem. Alternatively you need to know the other angles. Then you can use the appropriate trig function to find the length of the hypotenuse.
The length of one leg of a right triangle is 10ft and the length of the hypotenuse is 2 ft longer than the other leg What is the length of the hypotenuse and the other leg?
If the other leg has length X. Knowing the rule for triangles a^2+b^2=c^2 and that hypotenuse is x+2 10^2 + X^2 = (X+2)^2 you can solve to find X = 24 and the hypotenuse is 26.
A right triangle has a hypotenuse of length 17 and a leg 11 what is the are of the triangles?
The area is 71.29 square units
Are some right triangles are also equilateral triangles?
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
