\( \rm A \ right \ angled \ triangle \ has \ sides \ {\it X, \ Y} \ and \ {\it Z}, \ where \ {\it Z } \ is \ the \ hypotenuse \ and \ is \ 62 \ cm. \\ The \ angle \ between \ {\it X} \ and \ {\it Z} \ is \ 30 ^\circ ,\ what \ is \ the \ length \ of \ side \ {\it Y}\ ?\)

\( \rm{ A \ right \ angled \ triangle \ has \ shortest \ side \ 7 \ cm. \\ If \ the \ angle \ between \ the \ shortest \ side \ and \ the \ hypotenuse \ is \ 65^{\circ}, \ what \ is \ the \ length \ of \ the \ hypotenuse? } \)

\( \rm The \ two \ shortest \ sides \ of \ a \ right \ angled \ triangle \ are \ 9 \ cm \ and \ 11 \ cm. \\ What \ is \ the \ smallest \ of \ the \ internal \ angles? \)
