# What is the length of the hypotenuse of a right triangle if the legs have a length of 4cm?

Hypotenuse = sqrt(4 2 + 4 2 ) = 4*sqrt(2) = 5.7 (approx).

# What is the length of the hypotenuse of a right triangle if the legs have a length of 4?

To get the hypotenuse you need to square the twoo legs and add them together. Then that final answer, you find the square root of, and that's your FINAL answer. If both leg

# What is the length of the hypotenuse of a right triangle that has legs with lengths of 5?

5 sqrt(2) = 7.071 (rounded)

# What is the length of the hypotenuse of a right triangle with legs of lengths 8 and 9?

Use Pythagoras: 8 2 +9 2 = 145 and the square root of 145 is about 12.04159456 length of hypotenuse = 12 units to 2 significant figures

1.414 ie root 2

4 x sqrt2

# What is the length of the hypotenuse of a right triangle that has legs with length of 5 and 4?

Square root of 41

# What is the length of the hypotenuse of a right triangle that has legs of 5 and 4?

Abraham Pythagoras: H 2 = 5 2 + 4 2 ie 25 + 16 so H = sqrt 41, just over 6.4

# What is the length of the hypotenuse of a right triangle with legs of 7 and 8?

the length of the hypotenuse is 10.63

# What is the length of the hypotenuse of a right triangle with legs of 12 and 18?

Use Pythagoras' theorem: 18 2 +12 2 = 468 and the square root of this is the hypotenuse which is about 21.63330765 units in length

# What is the length of the hypotenuse of a right triangle with sides 233 and 657?

Using Pythagoras it works out to about 697 units of length

# What is the length of the hypotenuse of a right triangle with leg lengths of 5inches and 12 inches?

Using Pythagoras it is 13 inches
