Question

13POINTS!!!

Answer 1

Answer:

When we know all 3 sides we use the law of cosines

a = 47  

b = 11  

c = 38

cos (A) = (b^2+c^2-a^2)  / (2bc)

cos (A) = -0.7703349282

Angle A = 140.38

cos (B) = (a^2 + c^2 -b^2) / (2ac)

cos (B) =  0.9888017917

Angle B = 8.5826  degrees

cos (C) = (a^2 + b^2 -c^2) / 2ab

cos (C) = 0.8568665377

cos (C) = 31.033 degrees

Angle W would be the smallest angle so it equals

31.033 degrees or rounded to nearest tenth

31.03
