Question

at what range will radarset show plane flying at 10km above the ground and at a distance of 18 km from the radar station​

Answer 1

Answer:

Explanation:

As the fighter plane flies at 3 Km above the centre, it is at a straight line from the ground and as it moves a distance of 4 Km, the range of the radar forms a right angle involving the original point and the new location.

Hence, the distance of the plane from the radar can be found out by using Pythagoras’ theorem.

So this range is calculated as square root of (42 x 32 ) = 5 Km
