From the picture you can see that, ∠ ADB=30°and in triangle ADB:
3x+x+30=180°. From here you find that x=35°.
Now it is easy to find z from ABC 4x+z=180°, z=30°
Find y yourself.
2y+z=180° y=75°

Hi Bobosharif,
could you please explain how sum of angles in the triangle ADB are equal to 180? I mean
Angle A is divided into 2 parts : one with a angle ‘x’ ( that’s already given) and lets say other angle is ‘c’. Then sum of angles in triangle ADB would be 3x+(x+c)+30=180.

Hello Amrutha,
Thank you for your comments. You are absolutely right. There is a mistake in my solution.
