The required length of the hypotenuse of the triangle is √19.
<h3>What is a right triangle?</h3>
A right triangle, sometimes known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides.
To find the required length of the hypotenuse of the triangle:
Legs in the right triangle refer to the perpendicular and base.
Hypotenuse:
Therefore, the required length of the hypotenuse of the triangle is √19.
