The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?
1 answer:
For a polygon with n sides, the interior angles add up to:
(n - 2) x 180
an octagon has 8 sides:
(8 - 2) * 180 = 6 * 180 = 1080
from the question,1 side measures 2x while 7 sides measure x. this means
7x + 2x = 1080
9x = 1080
x = 1080/9
x = 120°
if x=120°
2x=2(120°)=240°
so, the seven smaller angles are 120°. while the one larger angle is 240°

Answer:
switch sides
-g+2/5UA=5b
add g to both sides
-g+1/5UA+g=5b+g
simplify
1/5UA=5b+g
multiply both side by 5
5×1/5UA=5×5b+g
simplify
AU=25b+5g
divide both sides by U
AU/U=25b/u+5g/u =U/U=0
simplify
A=25b+5g/U

Answer:
the answer would be 1/15, or approximately 0.067.
Step-by-step explanation:
Answer:
1/-2
Step-by-step explanation:
To find the slope:
rise/run
From point to point
So....
From (-1,0)
you go up 2(2)
then left 4(-4)
to get to (-5,2)
so 2/-4 reduced is 1/-2
The 2 angles at a vertex are supplementary (one interior and one exterior) the exterior angle is = the the sum of the 2 remote interior angles..
