If we let

pages. We know that this number of pages is 231, so we have
Answer:
1/4
Step-by-step explanation:
i think i might be wrong but im trying im not the best at this but there you go
First multiply them all by 8
2x - 1 = 7 + 4x
Subtract 2x
-1 = 7 + 2x
Subtract 7
-8 = 2x
Divide by 2
X = -4
<span>he total number of internal degrees is (n-2)*180 = 4*180 = 720 degrees.

let a = one of the congruent angles.
you have:
angles 1, 2, and 3 = a.
-----
if a = 2 * angle 4, then angle 4 = 1/2 * a
-----
if a = 1/2 * angle 5, then angle 5 = 2 * a
-----
we have:
angle 1 = a
angle 2 = a
angle 3 = a
angle 4 = 1/2 * a
angle 5 = 2 * a
angle 6 = 115
</span><span>-----
since the sum of the angles is equal to 720, we have:
3*a + 2*a + 1/2*a + 115 = 720
combine like terms to get:
5.5 * a + 115 = 720
subtract 115 from both sides to get:
5.5 * a = 720 - 115 = 605
divide both sides by 5.5 to get:
a = 720/5.5 = 110
-----
angle 1, 2, and 3 are each 110 degrees.
angle 4 = 55 degrees
angle 5 = 220 degrees
angle 6 = 115 degrees
-----
the question is:
What is the measure of the smallest angle?
the answer is:
55 degrees.</span>
