Answer:
7x^2+4x-5
Step-by-step explanation:
d=c-11
Step-by-step explanation:
d is desk
c is chair
The height of the d (desk) is always going to be 11 inches shorter than the chair. So subtract 11 from c (chair) and you will find d (desk).
If the chair is 13 inches....
d=13-11
d=2
If the chair is 32
d=32-11
d=21
This equation will work with numerous numbers to find the size of the desk. If you want you can find the height of the chair as well!

Answer: Approximately 35.54 degrees</h3>
=============================================================
Explanation:
With respect to reference angle x, the 5 is the opposite side, and the adjacent side is 7 units long.
We'll use the tangent ratio here
tan(angle) = opposite/adjacent
tan(x) = 5/7
x = arctan(5/7)
x = 35.5376777919743 approximately
x = 35.54
I rounded to two decimal places, but you can round however you need to or however your teacher instructs. Arctangent is the same as inverse tangent. Be sure that your calculator is in degree mode.
