According to the Pythagorean theorem,

 

a2 + b2  =  c2     , where  " c "  is the hypotenuse of a right triangle, and  " a "  and  " b "  are its legs.

 

They tell us that   b = √77   and   c = 12  . Plug these values in for  b  and  c  .

 

a2 + √772  =  122              This is...

 

a2 + 77  =  144                  Subtract  77  from both sides of the equation.

 

a2  =  67                            Take the positive square root of both sides.

 

a  =  √67

 

a  ≈  8.19
