A right triangle has sides of a, b, and 9, respectively, where a and b are both integers. What is the value of (a + b)?  Choose the correct choice from the following choices
A) 64  B) 49  C) 96  D) 81  E) 72
LET a= hypotenuse , b =base ,9 = perpendicular . therefore a^2 -b^2 =9^2 or (a+b)(a-b) = 81   a+b =81/a-b ' a-b cannot be zero ..therefore a+ b =81 where a-b is equal to 1   81
