Question

the length a pole below the earth. is two -fifth of it's length above the earth if the length of the pole is 49m find the length of the pole below the earth​

Answer 1

Answer:

14 m

Step-by-step explanation:

let the length of the pole above the earth be x

length of pole below the earth will be 2/5 x

total length of pole is 49 m

$x + \frac{2}{5} x = 49 \\ \frac{5x + 2x}{5} = 49 \\ 5x + 2x = 49 \times 5 \\ 7x = 49 \times 5 \\ x = \frac{49 \times 5}{7} \\ x = 7 \times 5 \\ x = 35 \: m$

length of pole above the earth is 35 m

length of pole below the earth is 2/5 x

= 2/5 × 35

= 2 × 7

= 14 m

hope you get your answer
