well, let's notice something, we have two 45° angles, now each of those will give use an equal opposite side, namely if that one side is "x", the other is her twin, "x" as well.

is a right-triangle, so we can use the pythagorean theorem, and we know the sides are x,x,6.

$\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies 6^2=x^2+x^2 \qquad \begin{cases} c=\stackrel{hypotenuse}{6}\\ a=\stackrel{adjacent}{x}\\ b=\stackrel{opposite}{x}\\ \end{cases} \\\\\\ 36=2x^2\implies \cfrac{36}{2}=x^2\implies 18=x^2\implies \sqrt{18}=x\implies \sqrt{9\cdot 2}=x \\\\\\ \sqrt{3^2\cdot 2}=x\implies \boxed{3\sqrt{2}=x}$

Find QR. A).12 B).-8 C).9 D).6

mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

$\sf 3 + 2x + 22 = x + 17$

$\sf 2x + 25 = x + 17$
$\sf 2x - x = 17 - 25$
$\sf x = - 8$

Now that we found x, let's find QR :-

QR = 2x + 22

$\sf QR = 2( - 8) + 22$
$\sf - 16 + 22$
$\sf 6$

Therefore, QR = 6 !!!

See below

Step-by-step explanation:

$13) \: no \: of \: people = 2 \div \frac{1}{8} \\ = 2 \times \frac{8}{1} \\ = 16 \\ \\ 14) \: no \: of \: prizes \: won \: by\:Mallory \\ = \frac{2}{ \cancel3} \times \cancel6 \\ = 2 \times 2 \\ = 4 \\ \\ 15) \: no \: of \: quart \: diced \: tomatoes \\ = 5 \frac{1}{4} \times 1 \frac{2}{3} \\ \\ = \frac{ \cancel{21}}{4} \times \frac{5}{ \cancel3} \\ \\ = \frac{7}{4} \times 5 \\ \\ = \frac{35}{4} \\ \\ = 8 \frac{3}{4} \\ \\ 16) \: no \: of \: blocks = 123 \frac{1}{2} \div 6 \frac{1}{2} \\ \\ = \frac{247}{2} \div \frac{13}{2} \\ \\ = \frac{247}{2} \times \frac{2}{13} \\ \\ \frac{247}{13} \\ \\ = 19$
