Question

In the right triangle, find the length of the side not given. Give an exact answer AND an approximation to three decimal places.
a=8 , b=10

Answer 1

is c the hypotnenuse? if so then use
\[c^2=a^2+b^2\]
\[c^2=8^2+10^2\]
\[c^2=64+100=164\]
\[c=\sqrt{164}\]

Answer 2

simplest radical form is
\[2\sqrt{41}\] and decimal is 12.806 from a calculator
