Given:
The length of the sides is a=18.3 cm,
The base of the triangle is b =3 cm.
Required:
We need to find the hypotenuse.
Step-by-step explanation:
Use the Pythagorean theorem.

Substitute a =18.3 and b=3 in the equation.


Take square root on both sides.


Length is always positive.

Final answer:
The hypotenuse is 18.54cm.
