Answer:

3:1 = 6:2 (x=2)

Step-by-step explanation:

Think of ratios as a fraction

3/1 = 6/x

to get from 3 to 6 you multiply it by 2. now for the ratio to be the same, you have to multiply the denominator by 2 as well. 2 x 1 = 2. therefore it would be 6/2. you can notice that if you simplify it, it is equal to 3/1. it is the same thing with ratios.

Find the length of DE. Round to the nearest hundredth. (Picture included)

LenKa [72]

Notice the picture
we have, the opposite side
the angle
and we want the hypotenuse

so recall your SOH CAH TOA $\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent} =$

which one has all that? low and behold, is Ms Sine,
so let's bother Ms Sine

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies sin(27^o)=\cfrac{18}{hypotenuse}
\\\\\\
hypotenuse=\cfrac{18}{sin(27^o)}$

make sure your calculator is in Degree mode, since the angle here is in degrees, as opposed to Radian mode
