Answer:

x = 13.5°

Step-by-step explanation:

Angles 2 + 3 = a straight line, so 180°

180 - 66 = 114 = angle 2

114 = 10x - 21

114 + 21 = 10x

135 = 10x

135 / 10 = x

13.5 = x

The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450
