Answer: f=78

Explanation:

En un cuadrilatero la suma de los angulos internos es 180°

Ademas los angulos alternos internos so iguales.

Por lo tanto el angulo frente a 72° en diagonal tambien es 72°

Si sumamos esos dos angulos obrenemos 144°Si restamos este resultado de 360° obtenemos 360°-144=216 °

Finalmente debemos dividir entre dos los 216°

216/2 = 78°
