How can i solve this? if you can explain in-depth, you.

Step-by-step explanation:

I didn't know this off of the top of my head, and I used Google to help me. Simply searching "30 60 90 right triangle" gave me a few very helpful links. For future reference, if no one is answering here, Google may be your friend.

The (credible) site that I found tells me

"The basic 30-60-90 triangle ratio is:

Side opposite the 30° angle: x

Side opposite the 60° angle: x * √3

Side opposite the 90° angle: 2x"

The side opposite the 30 degree angle is a value called "x" according to this site. This would mean that y is x, which is confusing, so we can just say that the value of y is y (if you want to go a little more in depth, I will simply be referring to what the site refers to as "x" as "y"). To begin, the side opposite the 30 degree angle, which is 8√3, is y * √3. This means that y is 8. Then, the remaining side is 2*y, which is 16.

Please let me know if you have any further questions or concerns.
