1. Answer:

   Now, In △DBC,

   DB=DC (Given)

   hence, ∠DBC=∠DCB=36

   ∘

   (Isosceles triangle property)

   Sum of angles of triangle = 180

   ∠DBC+∠DCB+∠CDB=180

   36+36+∠CDB=180

   ∠CDB=108

   Now, ∠ADC=180−∠ADB

   ∠ADC=180−108

   ∠ADC=72

   ∘

   in △ADC,

   ∠ADC=∠DAC=72

   ∘

   (Isosceles triangle property, AC= CD is given)

   Sum of angles = 180

   ∠ADC+∠CAD+∠ACD=180

   72+72+x=180

   x=180−144

   x=36

   ∘
