Answer 1

Hi there! :)
Can you please post the figure?

Answer 2

hello

Answer 3

Use the sine rule formula to find the angle ADB first
\[\frac{ \angle~ADB }{ 30 }=\frac{ 120degree }{ 35 }\]

Answer 4

u will get\[\angle~ADB=102.86degree\]

Answer 5

Then,use the angle ADB to find the angle ADC

Answer 6
