Answer:
The measure of the sum of interior angles of a 11-gon is 
.
Each interior angle is approximately 
.
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than 
.
But,
sum of interior angles of polygon = (n - 2) x
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x
= 9 x
=
Sum of angles of a 11-gon =
To check: convex polygons' interior angles are less than .
so that,
each interior angle of 11-gon = 
=
Answer:
y=70 degrees
Step-by-step explanation:
If 2 angles are complimentary, they add up to 90 degrees.
x+y=90 degrees
x=20 degrees
y=90-20 degrees
y=70 degrees
If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.
y=x
Substituting x for y, the equation is x+x+20=90
Since y is x, x would also be y, which is 35. then x+20 would be 55.
So y would be 35.
THE ANSWER WOULD BE <u><em>70 DEGREES</em></u>, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35
X y z, if it is a triangle= 180
if not, x+y+z cannot be answered, be more specific
Answer: 5²⁻⁵
<u>Step-by-step explanation:</u>
Well... the two rectangles are in the picture below, those are their coordinates
so, you can pretty much see how long one side is, since you can simply count the units on the grid
running a tests on them.... hmmm they'd be similar is the length of the corresponding sides on each figure, give the same ratio
