Question 953638

if the leg {{{a}}} of a right triangle is {{{4}}} units and the hypotenuse {{{c}}} is {{{9}}} units, to find the length, in units, of the other leg {{{b}}} of the triangle use Pythagorean theorem

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

{{{9^2=4^2+b^2}}}

{{{81=16+b^2}}}

{{{81-16=b^2}}}

{{{65=b^2}}}

{{{b=sqrt(65)}}}

{{{b=8.06}}} units
