To find the length of a hypotenuse (the side of a triangle opposite to the right angle) you need the two shorter sides lengths which i will call A and B.

X2=A2+B2

X2=A+B

X2=(A+B)

X=Find the square root of (A+B)

X=The square root of (A+B)

### 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

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...

### Find hypotenuse only using opposite and angle?

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.

### How do I find the length of the hypotenuse with one leg equalling 12 and the opposite angle being 30 degrees?

Rearrange the sine ratio of sine = opposite/hypotenuse:
hypotenuse = opposite/sine
hypotenuse = 12/sine 30 degrees = 24
Therefore the hypotenuse is 24 units in length.

### How can you find the base of a right triangle when you have the height and hypotenuse?

The square of the length of the base plus the square of the
length of the height will equal the square of the length of the
hypotenuse of your right triangle, per Pythagoras. Square the
hypotenuse, subtract the square of the height, and then find the
positive square root of that and you'll have the base of your right
triangle.
