Hi!

-\frac{4}{5}/2

-\frac{4}{5} /\frac{2}{1}

-\frac{4}{5}*\frac{1}{2}

=-\frac{2}{5}

Explanation: <em><u>First you had to convert element to fraction is 2=2/1 ,and it gaves us -4/5÷2/1. Then apply to the fraction rules, -4/5 *1/2=-2/5 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie </u></em>

Use the pythagorean theorem formula: a^2 + b^2 = c^2
c is the longest side of a triangle.
Plug 14 and 11 into a and b and find c.

14^2 + 11^2 = c^2
196+121=317
Square root it.
and you get square root of 317
