Answer:
4.46
Step-by-step explanation:
As the circumference of a circle is pi multiplied by the diameter to work out the radius you would first divide the circumference of 28 by pi, which gives you 8.92. This is the diameter, however the question is asking for the radius. To work out the radius you would divide the diameter by 2, which gives you 4.46. This is because the radius is half of the diameter.
1) Divide 28 by pi.
2) Divide 8.92 by 2.

Step-by-step explanation:
<u>Right Triangle </u>
It's a special type of triangle where one of its internal angles is 90°. The basic trigonometric formulas apply to relate lengths and angles. If h is the opposite side to the angle \theta, and x is the adjacent side of the same angle, then
Or, equivalently
The helicopter, ground and the two soldiers form two right triangles, as shown in the image below. Let's call x1 the distance from soldier 1 to the point O, then
Now for x2, the distance from soldier 2 to the point O
The distance between the soldiers is
