Answer:

\displaystyle   4 \sqrt{13}in

Step-by-step explanation:

we are given a right angle triangle and we want to figure out the missing <u>hypotenuse</u><u> </u>in order to do so we can consider using<u> </u><u>Pythagoras</u><u> theorem</u> given by

\displaystyle  {a}^{2}  +  {b}^{2}  =  {c}^{2}

\displaystyle    \implies{c}^{}  =  \sqrt{ {a }^{2}  +  {b}^{2} }

let a and b be 8 and 12 respectively thus

substitute:

\displaystyle   {c}^{}  =  \sqrt{ {8 }^{2}  +  {12}^{2} }

simplify squares:

\displaystyle   {c}^{}  =  \sqrt{ 64 +  14 4}

simplify addition:

\displaystyle   {c}^{}   =  \sqrt{208}

by simplifying the redical expression we obtain:

\displaystyle   {c}^{}   = 4 \sqrt{13}

Answer:

14.4 inches

Step-by-step explanation:

Use the Pythagorean theorem: a^{2} + b^{2}

So, this will be: 8^{2} + 12^{2} = c^{2}

By simplifying we get:

c = \sqrt{208}

The missing side is: 14.4 (rounded to the tenth)
