5 m.
Using Pythagoras:
Hypotenuse2 = side2 + other_side2
⇒ Hypotenuse = √(side2 + other_side2)
= √((3 m)2 + (4 m)2)
= √(9 m2 + 16 m2)
= √(25 m2)
= 5 m
3, 4, 5 is a well known Pythagorean triple - the three sides of a right angle triangle (32 + 42 = 9 + 16 = 25 = 52)
Another is: 5, 12, 13 (52 + 122 = 25 + 144 = 169 = 132)
If you multiply each of these sides by the same number (that is scale the triangle) you get other Pythagorean triples, eg
3, 4, 5 → (x2) 6, 8, 10; (x3) 9, 12, 15; (x4) 12, 16, 20; etc are all Pythagorean triples
5, 12, 13 → (x2) 10, 24, 26; (x3) 15, 26, 39; (x4) 20, 48, 52; etc are also all Pythagorean triples.

What is Circumradius of a right angled triangle?
The circumradius of a right angled triangle would be equal to half the length of its hypotenuse.
How do you measure a hypotenuse?
Use Pythagoras' theorem...a2 + b2 = c2where c is the length of the hypotenuse in a right-angled triangle.
Is a hypotenuse short?
It may be of any length but it is always the longest side in a right-angled triangle.
What's the equation to find the length of a hypotenuse of a triangle?
The basic equation for the hypotenuse of a right angled triangle is A squared plus B squared equals C squared. Where A and B are the two non hypotenuse sides and C is the hypotenuse. To find other lengths and angles of a triangle various functions in the branch of mathematics known as trigonometry is used.
What is the length of a leg of a right triangle with hypotenuse equals 22.5km and leg equals 44.7mm?
A hypotenuse should not be shorter than a leg length.
What is Circumradius of a right angled triangle?
The circumradius of a right angled triangle would be equal to half the length of its hypotenuse.
What is the length of a hypotenuse?
A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.
What is the length of the hypotenuse of the right triangle if AC equals 6 and AD equals 5?
The length of the hypotenuse of a right triangle if AC equals 6 and AD equals 5 is: 7.81

How can you calculate the length of the hypotenuse of a right angle triangle?
By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!
What is the length of a leg of a right triangle with hypotenuse equals 22.5km and leg equals 44.7mm?
A hypotenuse should not be shorter than a leg length.
What is the ratios function of sin?
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
How do you construct a 3 4 5 triangle Read?
It will be a right angled triangle with sides of 3 and 4 units with an hypotenuse of 5 units in length.
How do you find the length of the third side of a right angled triangle?
a2 +b2 = c2 (c is the longest side/or hypotenuse)
