Question

find the x if 5²+x²=13²​

Answer 1

Answer:

answer is x=12

Step-by-step explanation:

x^2=13^2-5^2

therefore x=under root of 169-25=144=12

Answer 2

Answer:

${5}^{2} + {x}^{2} = {13}^{2}$

$that \: \: is \: {x}^{2} = {13}^{2} - {5}^{2}$

$that \: \: is \: {x}^{2} = (13 - 5)(13 + 5)$

$that \: \: is \: {x}^{2} = 8 \times 18$

$that \: \: is \: x = \sqrt{144}$

$that \: \: is \: x = 12$

$hence \: \: your \: \: answer \: \: is \: \: x = 12$
