(A) The given triangle is a right-angled triangle with hypotenuse $h = 5 \ cm$ and one angle $	heta = 53^{\circ}$.Using trigonometric ratios:The side opposite to $53^{\circ}$ is $x = h \sin(53^{\circ}) = 5 	imes \frac{4}{5} = 4 \ cm$.The side adjacent to $53^{\circ}$ is $y = h \cos(53^{\circ}) = 5 	imes \frac{3}{5} = 3 \ cm$.The perimeter of the triangle is the sum of its sides: $P = 5 + 4 + 3 = 12 \ cm$.Thus,the correct option is $A$.

Find the perimeter of the triangle shown in the figure (in $cm$).
