A window is in the shape of a kite. caleb wants to apply a layer of plastic film on the top half of the window so that the glass
appears crackled. what are the dimensions of the layer of film he will apply? a kite is broken into 2 triangles. each triangle has a base of 18 inches and a height of 7 inches. 9 inches in width and 7 inches in height 9 inches in width and 14 inches in height 18 inches in width and 7 inches in height 18 inches in width and 14 inches in height
Let x-------------> amount added <span>to each side </span>A-------------> area increased----------> 84 ft²
we know that A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x² 50+15x+x²=84----------> x²+15x-34=0 <span>solving the second order equation </span>x1=-17 x2=2
