Los lados de un cuadrilátero mide 6,8,7,9con tal como se muestra en la figura si se realiza una producción sensual y al lado correspondiente a 7ck haora mide 12cm ¿cuánto debe medir los demás lados

Step-by-step explanation:

Step one:

given that the sides of the quadrilateral are:

6,8,7, and 9 in dimension.

And the side corresponding to 7 now measures 12

we may agree that the side has increased by 5cm, hence 5 has been added to that side.

Step two:

we can say that  the other side will increase as follows

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
