Question

1). a=6 b=7 c=11 Find A, B, C

2) a= 4 c=6 B=30 Find b, A, C

3) Solve the following triangle using either the Law of Sines or the Law of Cosines

b=9 c=13 A=58

Answer #1

1. Let the angles of a triangle be α, β, and
γ, with opposite sides of length a, b,
and c, respectively. Use the Law of Cosines and the Law of
Sines to find the remaining parts of the triangle. (Round your
answers to one decimal place.)
α = 105°; b =
3; c = 10
a=
β= ____ °
γ= ____ °
2. Let the angles of a triangle be α,
β, and γ, with opposite sides of length
a, b,...
