Option A:
is the length of the hypotenuse
Step-by-step explanation:
From the figure, we can see that the given triangle is a right angled triangle.
Hence, we can determine the length of the hypotenuse using Pythagoras theorem.
Thus, we have,
where a and b are the lengths of the sides of the triangle. And c is the hypotenuse.
Thus, substituting the lengths of the sides
,
and
is the hypotenuse.
Substituting these values in the equation, we get,
Thus, the length of the hypotenuse is
