Question

aplique o teorema de Pitágoras e determine x.
Em anexo!

Answer 1

a) x² = 21² + 28²
x² = 1225
x = 35

b) 25² = 24² + x²
x² = 625 - 576
x² = 49
x = 7

c) 15² = x² + 9²
225 = x² + 81
x² = 225 - 81
x² = 144
x = 12

d) x² = 6² + 8²
x² = 36 + 64
x² = 100
x = 10

e) 20² = x² + 16²
400 = x² + 256
x² = 144
x = 12

Answer 2

Teorema de Pitágoras = hip²=cat²+cat²

a)$x^2=28^2+21^2$
$x^{2}=784+441$
$x= \sqrt{1225}$
$x=35$

b)$25^2=24^2+x^2$
$x^{2} =25^2-24^2$
$x^{2} =625-576$
$x^{2} =49$
$x= \sqrt{49}$
$x=7$

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

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

e)$20^{2} =16^2+ x^{2}$
$x^{2} = 20^{2} -16^2$
$x^{2} =400-256$
$x= \sqrt{144}$
$x=12$
