Two patrol boats leave Cape May at the same time, the same speed, but on different bearings. One has bearing 41°45
VMariaS [17]

Based on the information given, the computation shows that the distance between them is 2.47 miles.

<h3>Solving the distance.</h3>

Since one has bearing 41°45', this will be: = 41° + (45/60) = 41° + 0.75 = 41.75°.

The other has bearing 59°13'. This will be:

= 59° + (13/60) = 59° + 0.22 = 59.22°.

The difference of the angles will be:

= 59.22° - 41.75°

= 17.47°

Let the distance between them be represented by c. Therefore, we'll use cosine law to solve the question. This will be:

c² = a² + b² - 2ab cos 17.47°

c² = 20² + 20² - (2 × 20 × 20 × 0.19)

c² = 6.07459

c = 2.47

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
Monica [59]

Answer:

PQ = 42

Step-by-step explanation:

Given

PT = 3x + 3

TQ = 5x - 9

Midpoint, T

Required

Determine PT

First, the value of x has to be calculated;

Since T is the midpoint, then:

PT = TQ

This implies

3x + 3 = 5x - 9

Solve for x

3x - 5x = -3 - 9

-2x = -12

x = -12/-2

x = 6

Length PQ can then be calculated using:

PQ = PT + TQ

PQ = 3x +3 + 5x -9

Collect Like Terms

PQ = 3x+ 5x +3  -9

PQ = 8x -6

Substitute 6 for x

PQ = 8 * 6 - 6

PQ = 48 - 6

PQ = 42
