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>

Answer:
x=-32/29
Step-by-step explanation:
3x+4y=36 Equation 1
-5x+3y=35 Equation 2
Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows
9x+12=108 equation 3
-20x+12y=140 equation 4
Subtracting equation 3 from equation 4 we obtain
-29x=32
x=-32/29
To find the value of y, we substitute the value of x into equation 2 as initially given in the equation
-5(-32/29)=35-3y
-5(-32/29)-35=-3y
