Y - y1 = m (x - x1)
m = 4 , x1 = 1 and y1 = 3, so its
y - 3 = 4(x - 1)
Answer:
True.
Step-by-step explanation:
The artists is using simple math. When cutting squares from the corners he uses the same measure for each side of the figuer (because is a square) and the remaining sides thatare folded havethe same measures as the squares.

Answer: 
Step-by-step explanation:
Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.
By definition each interior angle of a Regular polygon is given by:
(In degrees)
Where "n" is the number of sides of the polygon.
In this case you know that the polygon shown in the picture is a Decagon, which means that it has 10 sides. Then:

Therefore, you must substitute that value of "n" into
and then you must evaluate.
Through this procedure, you get that the measure of an interior angle of the Regular Decagon is:
