Choices:<br> A)8<br> B)10<br> c)15<br> D)17<br><br> Please explain not only answers
kykrilka [37]

Answer:

This is a tough one, I already know that GD is congruent to FG, so in order to find GD, you use pythagorean theorem, which will be GD^2+15^2=17^2 or 17^2-15^2=GD^2, which is 64 and square root tht is 8. Next, given that CD=15 and CD is Congruent to BC, this meant that BG must be congruent to GD and therefore BG must equal 8

Step-by-step explanation:

I hope this helps

If x/y = -3, then find x²/y² + y²/x².​
sladkih [1.3K]

Answer:

9.11

Step-by-step explanation:

Given that,

\dfrac{x}{y}=-3

We need to find the value of \dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}

The value of \dfrac{y}{x}=\dfrac{-1}{3}

So,

\dfrac{x^2}{y^2}+\dfrac{y^2}{x^2}=(\dfrac{x}{y})^2+(\dfrac{y}{x})^2\\\\=(-3)^2+(\dfrac{-1}{3})^2\\\\=9+\dfrac{1}{9}\\\\=9.11

So, the required answer is equal to 9.11.
