Question

if distance between two poles in the ground is 8 meter and their height are 10 cm and 6 cm then find the distance between their tops​

Answer 1

Answer:

That's hope it helps you

Answer 2

Answer:

4√5

Step-by-step explanation:

  Given:   height of first pole = AB = 6m

Height of second pole        = CD = 10m

Distance b/w feet of poles = AC = 8m

To find:-   Distance b/w the top of the poles , i.e.,BD

solution  :-  

let we draw a line BE perpendicular to DC i.e BE DC

since AC is also perpendicular to DC as pole is vertical  to ground,      

So,  BE=AC=8m

Similarly , AC=EC=6m

Now,

DE=DC-EC

DE=10-6

DE=4M

Since angle BED = 90o as BEperpendicular DC

Triangle BED is right triangle

Using pythagoras therom in right angle triangle AEB

(hpotenuse)2    = (height)2   +(base)2      

(BD)2                  = (4)2 +(8)2

(BD)2                 = 16+64

(BD)2                 = 80

BD                     = 4√5

Hennce, the distance b/w tops of the pole = 4√5 meter
