Question

calcule os valores de X ,Y e z dos triângulos acima( me ajudem que souber fazer) preciso muito !!!!!!!!!​

Answer 1

a)

${z} ^{2}=3.5 \\ z=\sqrt{15} \\ {x} ^{2}=8.3 \\{x} ^{2}=24 \\ =2\sqrt{6}$

$8.\sqrt{15}=2\sqrt{6}.y \\ y=\frac{8\sqrt{15}}{2\sqrt{6}} = 2\sqrt{10}$

b)

${x}^{2} = 12.3 \\ x = \sqrt{36} \\ x = 6$

${z}^{2} = 3.9 \\ z = \sqrt{3.9} \\ z = 3 \sqrt{3}$

$12. 3\sqrt{3} = 6.y \\ y =\frac{36 \sqrt{3} }{6} \\ y = 6 \sqrt{3}$

c)

${12}^{2} = 9.(z - 9) \\ z - 9 = \frac{144}{9} \\ z = 16 + 9 \\ z = 25$

${x}^{2} = 25.16 \\ x =\sqrt{25.16} \\ x = 5.4 \\ x = 20$

$25.12 = 20y \\y = \frac{300}{20} \\ y = 15$
