Answer:
The Answer to your problem is 3 √ 2
Step-by-step explanation:
Step 1. Find 0 ( helps to plot z on complex plane)
z is in quadrant 4
0 is between -/z and 0
Step 2. Find modulus |z|
|z|= check mark 3 to the power of 2 + (-3) power of 2 = check mark, 9+9 = check mark 18 =check mark 9.
Step 3. Write out z in polar form
z = 3 check mark 2.

Answer:
78.4 ft
Step-by-step explanation:
Part I:
Missing angle = 180° - (130 + 30) (sum of angles in a triangle)
= 180° - 160°
Missing angle = 20°
Part II: distance (d) from Swanson to the boat
Law of Sines is given as:
Where,
a = d
A = 130°
b = 35 ft
B = 20°
Plug in the values and solve for d
Multiply both sides by sin(130) to make d the subject of the formula
