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

Answer:
110
Step-by-step explanation:
120+50+80+x= 360
250+x= 360
x= 360-250
x= 110
