Answer:
$510
Step-by-step explanation:
I'm not sure what you mean by "now $90 price regular price
," but I'm going to assume it means that's the discount.
So if $90 is the discount and $600 is the regular price, all you have to do is subtract 90 from 600 and you get $510.
True.
The angles must be equal. If the angles are not equal they can not be similar.
From the figure attached with this answer have octagon ABCDEFGH.
We can make a cut to create a plane section in the following shapes:
1. Rectangle
Here ADEH form a rectangle. To make rectangle we take ADEH
2. Octagon
For getting Octagon just cut ABCDEFGH form octagon
3. Triangle
To get triangle cut opposite diagonals. From the figure we can see AOB,BOC,COD,DOE,EOF,FOG,GOH and HOA are triangles.
4. Trapezoid
To get trapezoid ABCD form trapezoid and EFGH form another trapezoid
