Question

the legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse? Select one: a. square root 33 units b. square root 65 units c. 33 units d. 65 units

Answer 1

$\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ c=\sqrt{4^2+7^2}\implies c=\sqrt{65}$

Answer 2

The answer is

b. square root 65 units

because those were the only choices but after you square root the answer will be 4225

but as of now and the choices we have its

b. square root 65 units
