Answer:
x = 10
Step-by-step explanation:
it has 8 sides so:
total interior angle degrees = (180° x 8 sides) - 360° = 1080°
11x + 14 + 4x + 87 +2x + 70 + 4x + 31 + x + 92 + 3x + 167 + 5x + 48 + 2x + 251 = 1080°
combine like terms:
32x + 760° = 1080°
subtract 760° from both sides of the equation:
32x = 320°
divide both sides by 32:
x = 10
Answer:
Step-by-step explanation:
2*2*2 =
there is likely a number missing in what you said the width was equal, so you may need to plug in a number in the work I provide, if so.
A=x-16
W=x+1 (assuming it just wants any number to be able to be added to the 1)
We first need to use the area formula to setup the problem
A=W*L
area equals width times length
We can divide both sides by W to solve for L and get
A/W=L
from here we can just plug in the given values for area and the width
(x-16)/(x+1)=L
This should answer your question, but the x in the denominator may need replaced if the * in your given width is actually a different value besides x.
