Alika [10]

Answer:

The distance between them is 230.65 miles

Step-by-step explanation:

Here we use the Cosine formula

a^2 = b^2 + c^2 - 2bc\ cos\ A\\\\a^2 = 200^2 + 300^2 - 2\times 200\times 300cos50^{\circ}\\\\= 40,000 + 90,000 - 120,000cos50^{\circ}\\\\= 130,000 - 120,000 \times 0.64\\\\= 130,000 - 76,800\\\\a^2= 53,200\\\\a = \sqrt{53,200} \\\\= 230.65\ miles\ per\ hour

Now the distance for one hour is

= 230.65 ÷ 1

= 230.65 miles

Sonbull [250]

Answer:

The correct answer is option D.  48

Step-by-step explanation:

From the figure we can see that, some right angled triangles.

<u>To find the measure of LP</u>

Consider the right angled  triangle LPT,

LT is the hypotenuse, LP = 50 units  (given)

PT = QT = RT = 14 units

From figure we get,

LP² + PT² = LT²²

LP² = LT² - PT²

 = 50² - 14²

 = 2500 - 196

 = 2304

LP =√2304

 = 48

The correct answer is option D.  48
