The value of the interior angle of the regular polygon is calculated using the formula (n - 2) 180 / n where n is the number of sides of the regular polygon.
<u>Step-by-step explanation:</u>
A regular polygon refers to a multi-sided convex figure where all the sides are equal in length and all the angles have equal degree measures.
The triangle has 3 interior angles of 60 degrees
The square has 4 interior angles of 90 degrees.
The pentagon has 5 interior angles of 108 degrees .
The formula for the interior angle of a regular polygon is given by,
(
n
−
2
)
180 / n
where n refers to the number of sides.
Triangle : (3 - 2) 180 / 3 = 60 degree.
Square : (4 - 2) 180 / 4 = 90 degree.
Pentagon: (5 - 2) 180 / 5 = 108 degree.
Answer:
The correct option is (1).
Step-by-step explanation:
The given system of equation is,
..... (1)
.... (2)
The solution of the system of equation is the point where both line intersect each other.
Solve the equation by method of elimination.
Multiply equation 1 by 3.
... (3)
Add equation (2) and (3).
Put this value in equation 1.
Therefore, the lines intersect each other at (0.25,3.75). So, the first option is correct.
To find the length of the sides you have to find the square root of 225, I used a calculator and got 15 :)
Answer:
n × scale factor = n prime
n × 0.75 = n′
In other words per the equation above, a Scale Factor of 0.75 is the factor that you would multiply with n to get n′.
