Explicație pas cu pas:
a)
[tex] \frac{x}{3} = \frac{60}{y} = \frac{24}{18}[/tex]
[tex]\frac{x}{3} = \frac{24}{18} = > x = \frac{3 \times 24}{18} = > x = 4 [/tex]
[tex]\frac{60}{y} = \frac{24}{18} = > y = \frac{60 \times 18}{24} = > y = 45[/tex]
b)
[tex]\frac{5}{4} = \frac{10}{x} = \frac{5 \sqrt{2} }{z} = \frac{t}{904} [/tex]
[tex]\frac{5}{4} = \frac{10}{x} = > x = \frac{4 \times 10}{5} = > x = 8[/tex]
[tex]\frac{5}{4} = \frac{5 \sqrt{2} }{z} = > z = \frac{4 \times 5 \sqrt{2} }{5} = > z = 4 \sqrt{2} [/tex]
[tex]\frac{5}{4} = \frac{t}{904} = > t = \frac{5 \times 904}{4} = > t = 1130[/tex]
