Sale price: $66.30 percent of discount: 65%
find the regular price

$189.43

Step-by-step explanation:

P = regular price

65% as a decimal = = .65

Discount = .65

To get the amount of the discount we would multiply P * .65

To find the sale price we subtract the discount from the original price.

Now we write our equation:

P - P(.65) = $66.30  

Solve for P

P - P(.65) = $66.30  

1P - P(.65) = $66.30  

1P - .65P = $66.30  

.35P = 66.30   Divide each side by .35

.35P.35 = 66.30/.35

P = 66.30/.35

P ≈ $189.43

Step-by-step explanation:

we need much more information. you don't show us the diagram of the shape. for example.

it is impossible to know what you mean by a general angle between 3 points (?).

and we cannot even see the full screen shot.
