14.1 inch. is the length of the hypotenuse to the nearest 10th of an inch.
What is Pythagorean theorem?
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
here, we have,
Pythagoras theorem
a^2 + b^2 = c^2
10^2 + 10^2 = c^2
200 = c^2
Root(200) = c
c = 14.1 to the nearest tenth of an inch
hence, 14.1 inch. is the length of the hypotenuse to the nearest 10th of an inch.
