Y would equal 2
x would equal 6
In other words it is (6,2)

Find the missing side lengths. Leave your answers as radicals in simplest form.

The length of missing sides x = 5 units and y = 5 units.

<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>

In ΔABC,

AB (Base) = y , BC(Hypotenuse) = $5\sqrt{2}$ , CA (perpendicular) = x

and ∠ABC = $45^0$

Now,

tan $45^0$ = perp. / base

1 = x /y

x= y .................(i)

again,

sin $45^0$ = perp. / Hypo.

$\frac{1}{\sqrt{2} } = \frac{x}{5\sqrt{2} }$

x = 5

put in equation (i), we get

y = 5

Thus, the length of missing side of the given triangle is x = 5 units and y = 5 units.

Miley’s music has a sale on music CDs. All music CDs are discounted 15%. Mariana’s receipt indicates that she saved $3 on her CD

Tcecarenko [31]

she saved $3, and we know the discount is 15%, so her savings is that 15%, thus we know 15% of that purchase is 3.

let's say the full price is x, and therefore the 100%, if we know 3 is the 15%, what is x?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 3&15\\ x&100 \end{array}\implies \cfrac{3}{x}=\cfrac{15}{100}\implies \cfrac{3\cdot 100}{15}=x\implies 20=x$
