Answer 1

Answer:

tex] \begin{lgathered}\tt \implies \: (25 - x) {}^{2} = (x) {}^{2} + (5) {}^{2} \\ \tt \implies625 - 50 + x {}^{2} = x {}^{2} + 25 \\ \tt \implies - 50xused to produce fibre from plants like jute, flax, hemp stalks, and also coil from coconut husks. The short and long fibres obtained after retting are used widely to manufacture paper, ropes, and wallboards.
