We have the right angle triangle with sides:

The hypotenuse (h) = 30

One of the sides ( L) = 10

Find the other sides.

Let the other side be B:

Then we know that in a right angle triangle , the hypotenuse equals the square root of the sum of the sides squares:

==> hypotenuse^2 = side1^2 + side2^2

==> h^2 = L^2 + B^2

==> B^2 = h^2 - L^2

==> B = sqrt( h^2 - L^2)

= sqrt( 30^2 - 10^2)

= sqrt( 900 - 100)

= sqrt800

= 20sqrt2 *

Then, the length of the other sides is:

**B = 20sqrt2 = 28.3 ( to the nearest 10th)**
