Question

ultilizando as fórmulas acima calcule os valores das incógnitas​

Answer 1

Explicação passo-a-passo:

a)

$\sf b^2=m\cdot a$

$\sf x^2=9\cdot25$

$\sf x^2=225$

$\sf x=\sqrt{225}$

$\sf \red{x=15}$

b)

$\sf c^2=n\cdot a$

$\sf x^2=5\cdot9$

$\sf x^2=45$

$\sf x=\sqrt{45}$

$\sf \red{x=3\sqrt{5}}$

c)

$\sf a\cdot h=b\cdot c$

$\sf 5\cdot x=3\cdot4$

$\sf 5\cdot x=12$

$\sf x=\dfrac{12}{5}$

$\sf \red{x=2,4}$

d)

$\sf h^2=m\cdot n$

$\sf h^2=4\cdot16$

$\sf x^2=64$

$\sf x=\sqrt{64}$

$\sf \red{x=8}$
