Your answer is present on paper

Answer 2

$\boxed{\boxed{\boxed{\bold{\red{solution: \longrightarrow}}}}}$

Given,

ABC is a right Δ.

AB = 25 cm

AC = 7 cm

To find BC

By using pythagores theorem

$\bold{ {AC}^{2} = {AB}^{2} + {BC}^{2}} \\ \\ \bold{= > {7}^{2} = {25}^{2} + {bc}^{2}} \\ \\ \bold{= > {BC}^{2} = 625 - 49} \\ \\ \bold{= > {BC}^{2} = 576} \\ \\ \bold{= > BC = \sqrt{576} }\\ \\ \bold{= > BC = 24 \: \: cm}$
