Determine the angles
and 
and the length of side AB of the triangle. Note that there are two possible answers to this question and we have provided only one of them as an answer. = 46.7°, = 93.3° d = 9.22 = 50.0°, = 90.0° d = 9.14 = 40.0°, = 100.0° d = 9.22 = 48.6°, = 91.4°, d = 9.33Discussion:

Guys here we can't use trigonometry relations.
Because one of them angle is not 90°.
Because one of them angle is not 90°.

Why cant we use cos40=7/AB=>AB=9.14 directly......it is also correct method.

It would be better to give a small description for angles also...

Using sine formula,
a/sin A = b/sin B
6/sin 40 = 7/sin CBA
a/sin A = b/sin B
6/sin 40 = 7/sin CBA

sin 40'= 6/ab
AB= 6/SIN 40
AB= 9.33
option d
AB= 6/SIN 40
AB= 9.33
option d

COS40=7/AB
AB=7/COS40
AB=9.13
AB=7/COS40
AB=9.13
