Question

AJUDA PARRA FAZER ISSO PORFAVOR!!!!1

Answer 1

$a) sen30 = \frac{x}{10} =\frac{1}{2} \\\\x=5\\\\cos30=\frac{y}{10} =\frac{\sqrt{3} }{2} \\\\y=5\sqrt{3}$

$b)sen45=\frac{y}{4\sqrt{2} } =\frac{\sqrt{2} }{2} \\\\y=4\\\\cos45=\frac{x}{4\sqrt{2} } =\frac{\sqrt{2} }{2} \\\\x=4$

$c)sen60=\frac{x}{6\sqrt{3} } =\frac{\sqrt{3} }{2} \\\\x=9\\\\cos60=\frac{y}{6\sqrt{3} } =\frac{1}{2} \\\\y=3\sqrt{3}$

$d)sen45=\frac{6}{y} =\frac{\sqrt{2} }{2} \\\\y=6\sqrt{2} \\\\cos45=\frac{x}{6\sqrt{2} } =\frac{\sqrt{2} }{2} \\\\x=6$
