HELP the answer is not 48.5, 48.56, 48.565 or 48.5654 (or any other decimal places)
The question is the picture attached below

48.5654 degrees to the nearest ten thousandth.

Step-by-step explanation:

We can use the cosine  rule  to do this

First find m < C:

45^2 = 34^3 + 34^2 - 2.34.34 cos C

Cos C = [45^2 - (34^3 + 34^2 )] / (-2312)

= -287 / -2312

= 0.1241349

m < C = 82.8692 degrees

Therefore m < B = 180 - 82.8692) / 2      (as ABC is an isosceles triangle).

= 48.5654 degrees
