X = sprintf(('For a triangle of sides H, O and A,(Needs to be the answer picked from menu)

Does anyone know how once I pick from the menu, to make that answer a variable so I can use for sprintf like %s or something. Would be a huge help.

Use a cell array of strings. You can address the as any other array.

For example:

fcn_name = {'sin', 'cos', 'tan', 'cot', 'cosec', 'sec'};
T = 3;
str = sprintf('The value of %s = %.4f\n', fcn_name{T}, 0.3)

str =
The value of tan = 0.3000
