If a polygon is regular, it has congruent sides and congruent angles. We know that an octagon has 8 sides and a perimeter of 80cm. Because the sides of the octagon are congruent, we can divide 80 by 8 to get <u>10 centimeters for one side. </u> Hope this helps!! :)
Answer:
0 < x < 50
Step-by-step explanation:
We start out with a square (which IS a rhombus for all sides are equal in
length. That's when the diagonals are equal in length, which, by the
Pythagorean theorem equal to
5*√2
C^2=a^2+b^2
=25^2+25^2
Factorise
c^2=25^2 × 2
c=square root of 25^2 × 2
That is
c=√25^2 × 2
=5×√2
As we decrease the angle on the bottom left and increase the angle on
the bottom right, the green diagonal increases to 25+25 or 50, but never gets to 50. The red diagonal shrinks to 0 but never gets to 0.
the lengths of a diagonal can only be in the open interval from 0 to 50. In interval notation that is (0,50) or 0 < x < 50.
Answer: 36 customers
Step-by-step explanation:
I'm pretty sure because you have to multiply 40 x 6 which is 240 and 6 x 6 which is 36 to get your answer.
