Question

Determine the remaining sides and angles of the triangle ABC.
A = 15.85°
B = 34.45°
c=13.26 m
C=

Answer 1

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
