A right triangle has legs of lengths 6 and 15 inches. Find the length of the hypotenuse (nearest tenth).

zubka84 [21]

Answer:

The length of the hypotenuse is 16.2 inches.

Step-by-step explanation:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 6^{2} + 15^{2}$

$c^{2} = 36 + 225$

$c^{2} = 261$

$\sqrt{c^{2} } = \sqrt{261}$

$c = 16.2$
