HERE IS YOUR ANSWER...
I THINK THIS MAY SOLVE YOUR DOUBT....
THANK YOU......
1. Which polygon or polygons are regular?
A regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
Therefore your answer is:
A. equilateral triangle
C. square
2. Which polygon is always irregular?
traingle - NOT (equilateral triangle)
trapezoid - YES
square - NOT
hexagon - NOT (regular hexagon)

Answer: True</h3>
This is often how many math teachers and textbooks approach problems like this. The overlapped region is the region in which satisfies every inequality in the system. Be sure to note the boundary of each region whether you're dealing with a dashed line or a solid line. Dashed lines mean points on the boundary do not count as solution points, whereas solid boundaries allow those points as part of the solution set.
Side note: This is assuming you're dealing with 2 variable inequalities. If you only have one variable, you don't need to graph and instead could use algebra. Graphing doesn't hurt though.
Answer:
It is an identity, proved below.
Step-by-step explanation:
I assume you want to prove the identity. There are several ways to prove the identity but here I will prove using one of method.
First, we have to know what cot and cosec are. They both are the reciprocal of sin (cosec) and tan (cot).
csc is mostly written which is cosec, first we have to write in 1/tan and 1/sin form.
Another identity is:
Therefore:
Now this is easier to prove because of same denominator, next step is to multiply 1 by sin^2x with denominator and numerator.
Another identity:
Therefore:
Hence proved, this is proof by using identity helping to find the specific identity.
There are 8 faces on the figure.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 =
152.
Then, there is another side that equals 4 x 4 which is
24.
Another side equals 4 x 6 which is
24.
Another one equals 6 x 6 which is
36.
Another side equals 6 x 6 which also equals
36.
Another side equals 10 x 6 which is
60.
The last side is 10 x 6 which equals
60.
Which should add up to 392 in.
