Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem

we have

substitute

-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem

we have

substitute


----> equation B
equate equation A and equation B

solve for x

Simplify

<em>Find the length of DC</em>

substitute the given values

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>
