Answer:
Step-by-step explanation:
X. The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
The value of f(-6) is -3.
Your answers are
A = 35.7°
B = 67.6°
C = 76.7°
cosine law
A = 35.723697
sine law for the rest of the angles
B = 67.58886795
All angles in triangle sum to 180 so find C with that
A + B + C = 180
C = 180 - A - B
C = 180 - 35.723697 - 67.58886795
C = 76.7°
