Question

Two poles of length 29m and 50m are 20m apart. What is the distance between their top ?

Answer 1

Answer:

29 m

Step-by-step explanation:

According to the figure

AB = 29 m

BC = 20 m

CE = 50 m

But AB = DC

Therefore DC = 29

But ...

→CE - DC = DE

→50 - 29

→DE = 21 m-------(1)

According to the Figure

BC = AD

AD = 20 m---------(2)

Using the Pythagoras Rule by substituting (1) and (2)

AE² = AD² + DE²

AE² = 20² + 21 ²

AE² = 400 + 441

AE² = 841

Therefore...

AE = √841

AE = 29 m
