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.

[tex]53 + 90 = 143[/tex]

[tex]180 - 143 = 37[/tex]

So our missing angle (D) is 37°.

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

[tex] \sin(x) = \frac{opposite}{hypotenuse} [/tex]

Let's plug in our numbers,

sin(53°) = x over 27

X ≈ 21.56
