ON A TRINGLE FIND THE LENGTH

SL=20
H=12

1 answer

To find the length of the triangle side, we can use the Pythagorean theorem.

In this case, we have a right triangle with one side of length 20 (SL) and the other side of length 12 (H).
Let's label the unknown length as L.

According to the Pythagorean theorem:

L^2 = SL^2 - H^2

L^2 = 20^2 - 12^2
L^2 = 400 - 144
L^2 = 256
L = √256
L = 16

Therefore, the length of the triangle side is 16.
