Answer: C= 129.7 degrees
a=4.71m
b=9.75m
Angles must be supplementary and add up to 180.
Step-by-step explanation:
Then use law of sines to find other sides.
c/sin (C) = a/sin(A)
c/sin (C)=b/sin(B)
13.26/sin(129.7) = a/sin(15.85)
Cross multiply
a= 4.71m
13.26/sin (129.7)=b/sin (34.45)
Cross multiply
b= 9.75m
