QuestionUsing the Law of Sines to solve the all possible triangles if A=110,a=29,b=15\angle A=110^{\circ}, a=29, b=15. If no answer exists, enter DNE for all answers. B\angle B is \square degrees C\angle C is \square degrees c=c= \square

Studdy Solution
Calculate side cc using the Law of Sines:
asinA=csinC\frac{a}{\sin A} = \frac{c}{\sin C}
Substitute the known values:
29sin110=csin41.0\frac{29}{\sin 110^\circ} = \frac{c}{\sin 41.0^\circ}
Solve for cc:
c=29sin41.0sin110c = \frac{29 \cdot \sin 41.0^\circ}{\sin 110^\circ}
Calculate cc:
c290.65610.939720.3c \approx \frac{29 \cdot 0.6561}{0.9397} \approx 20.3
The solution for the triangle is:
B=29.0\angle B = 29.0^\circ
C=41.0\angle C = 41.0^\circ
c20.3c \approx 20.3
