Answer:
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
