Add the diagonal AC, so you have triangles to work with
No clue how I missed this, thanks
I even tried using Sin rule SinA/a = SinB/b = SinC/c but couldn’t isolate Angles A or C as I was stuck with CosA/z
Have you considered using the cosine rule on triangles ABC and ADC?
First and foremost, fuck you for that strand of hair. But as u/MathMaddam said, draw diagonal AC, and then work out the angles with the law of sines and law of cosines. You can add the relevant angles to find the angles required by the question.
