A rescue helicopter flew from its home base for 35 kilometers on a course of 330 degrees to pick up an accident victim. It then
artcher [175]
I've drawn a triangle to represent the journey (see attached.

The angle from Home to Victim to Hospital is:

a = 90 - (360 - 330) = 90- 30 = 60^o

Using the cos rule, we can solve for the length x:

a^2 = b^2 +c^2 - 2bccosA&#10;\\x^2 = 35^2+25^2-2(35)(25)cos60&#10;\\x^2 = 1850 - 875&#10;\\x^2 =  975&#10;\\x =  \sqrt{975}&#10;\\x = 31.2249...

Using the cos rule, we can solve for angle b:

a^2 = b^2 +c^2 - 2bccosA&#10;\\35^2 = 31.22...^2+25^2-2(31.22...)(25)cosb&#10;\\1225 = 975 + 625 - 1561.249...cosb&#10;\\-375 = -1561.249...cosb&#10;\\b = cos^{-1}( \frac{-375}{-1561.249...}) &#10;\\b = 76.1...

So the bearing the helicopter has to travel is:

270 - 76.1 = <u>193.9 degrees (1 dp)</u>

And the distance it travels is <u>31.2 km (1 dp)</u>

The amount of RENT forgot to write is $ 50.

<h3>What is Transaction?</h3>

A transaction is a completed agreement between a buyer and a seller to exchange goods, services, or financial assets in return for money.

Here, Total expected amount = $ 900

          Actual amount = $ 750

          Deposit forgot = $ 100

Amount of RENT = 900 - (750 + 100)

                              = 900 - 850

                             = $ 50

Thus, The amount of RENT forgot to write is $ 50.
