Question

hi guys can you find it !

ABC is a triangle,right-angled at C. If AB=25 cm and AC=7 cm,find BC​

Answer 1

Answer:

AB²=AC²+BC²

25²=7²+BC²

625=49+BC²

BC²=625-49

BC²=576

BC=24

Hope it helps

Step-by-step explanation:

Answer 2

Answer:

BC = 24cm

Step-by-step explanation:

Given :

ABC is a right angle triangle , right angled at C .

AB = 25cm

AC = 7cm

find :

BC = ???

solve :

we know that ,

by PGT

${(ab)}^{2} = {(ac)}^{2} + {(bc)}^{2}$

put the values of ab and ac

${(25)}^{2} = {(7)}^{2} + {(bc)}^{2}$

$625 = 49 + {(bc)}^{2}$

$625 - 49 = {(bc)}^{2}$

$576 = {(bc)}^{2}$

${(24)}^{2} = {(bc)}^{2}$

$bc = 24cm$

Hence the value of BC = 24cm
