The picture is blurry I could help but I can’t really see it
The initial diameter of the table is 42", but this diameter is to be extended by 8" (right and left), So the tablecloth will have a diameter of 42+8+8 = 58"
and the radius of the tablecloth = 24"
Hello!
As you can see, 3x+9 makes a right angle, or 90 degrees. We can turn this into an equation and solve for x.
3x+9=90
First we subtract 9 from both sides.
3x=81
Then divide both sides by 3.
x=27
Therefore, x=27.
I hope this helps!
