Answer: -37%

Step by Step Sol: 100=x

10% of 100 equals 10

100-10 = 90

30% of 90 equals 27

90-27 = 63

63-100 equals -37

Answer:

x = 34

y = $51\sqrt{3}$

Step-by-step explanation:

$sin30=\frac{17}{y}$

$y=\frac{17}{sin30} =\frac{17}{.5} =34$

$tan30=\frac{17}{x}$

$x=\frac{17}{tan30} =\frac{17}{\frac{\sqrt{3} }{3} } =(17)(3)\sqrt{3} =51\sqrt{3}$
