Question

Calcule o valor de X aplicando o Teorema de Pitágoras

Me ajudem por favooor! Fico muito agradecidaaa

Answer 1

a) $15^2=12^2+x^2\\225=144+x^2\\225-144=x^2\\81=x^2\\x=\sqrt{81} \\x=9$

b)$14^2=5\sqrt{3}^2+x^2\\ 196=75+x^2\\196-75=x^2\\x^2=121\\x=\sqrt{121} \\x=11$

c)$10^2=x^2+x^2\\100=2x^2\\x^2=100/2\\x^2=50\\x=\sqrt{50}\\ x=5\sqrt{2}$

d)$10^2=8^2+x^2\\100=64+x^2\\36=x^2\\x=\sqrt{36} \\x=6$
