ID Baseline

Question 5

Magnitude and Direction Problem 3

Answer 5

Spot 90DEG Rule
        180DEG Rule
        Duplicate Angles
        Z Rule
Label Everything

Question 6

Magnitude and Direction Problem 5

Answer 6

Resultant=New_Baseline^2+opp^2
Magnitude=sin^-1 (opp/Resultant)
Draw in Bearing cross
Run Bearing

Question 7

Magnitude and Direction Problem 4

Answer 7

Start on new Triangle
[Hypo] Cos [Angle] = [adj]
[Hypo] Sin [Angle] = [opp]
Add Baselines

Question 8

Sine Rule?

Answer 8

a/sinA = b/sinB = c/sinC
Let a be a known Angle
2 angles and 1 length
A = Angle a = Length

Question 9

Cosine Rule?

Answer 9

a^2=b^2+c^2-2bc Cos A
Let a be a known Angle
2 Length and 1 angle
A = Angle a = Length
