I've drawn a triangle to represent the journey (see attached.
The angle from Home to Victim to Hospital is:
a =
Using the cos rule, we can solve for the length x:
Using the cos rule, we can solve for angle b:
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>

Let assume two consecutive odd numbers 2x+1 and 2x+3
It is given their sum is 52.
So we can write equation as
On subtraction 4 on both sides of equation
x = 12
So the numbers are
first number is =
Second number is =
So the required numbers are 25 and 27.
