WHATTTTTTTTTTTTTTTTTTTTTTTTTTT
A.) it's a 90° angle
90=6x+4x+10
90=10x+10
-10 -10
80=10x
divide both sides by 10, x=8
B.) it's a 180° angle
180=5x+13+3x+7
180=8x+20
-20 -20
160=8x
divide both sides by 8, x=20
C.) it's a 180° angle
180=3x+5+2x+18+2x+17
180=7x+40
-40 -40
140=7x
divide both sides by 7, x=20
D.) it's a 180° angle
180=90+30+x
180=120+x
-120 -120
60=x
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!
