Okay so first let's find out our other angle. Since this is a triangle, it has 180°. We have two measurements already, 53° and 90°. To find the other angle simply add the angles and subtract by 180.

53 + 90 = 143

180 - 143 = 37

So our missing angle (D) is 37°.

To solve for our x we will be using the sine ratio and cosine ratio.

\sin(x)  =  \frac{opposite}{hypotenuse}

Let's plug in our numbers,

sin(53°) = x over 27

X ≈ 21.56

I hope that helps you out !!

Is the difference of two positive rational number always positive explain
Dominik [7]
No . . . while the difference represents the absolute magnitude between two numbers . . . for example . . .

<em>The difference between 5 and 2 is . . . 3</em>
<em>The difference between 6.4 and 9.5 is . . . 3.1</em>

 . . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative

. . . so in short . . . the answer is . . . <u><em>NO</em></u>

PLEASE HELP MEEEEEE PLEASEEEEEEEE!!!!!! IM TIMED
crimeas [40]

Set up an equation to solve.

$8.50x (since it is the rate of change) + $12 (flat fee) = total money earned (or y). In this case, we have the total, amount, and are looking for x. Plug $139.50 into the equation.

$8.50x + $12 = $139.50

Now, solve for x.

$8.50x + $12-12 = $139.50-12  > <em>$8.50x = $127.5</em>

$8.50/8.50x = $127.5/8.50 > <em>x = 15</em>

So, the correct answer is <u>D. Olivia babysat for 15 hours.</u>
