Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon =
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
Answer:
Each oven is discounted by $20.
Step-by-step explanation:
Original price of oven in dollars =
To find total cost for 9 such ovens without discount we will apply unitary method.
If 1 oven costs in dollars =
Then 9 ovens will cost in dollars =
The ovens are purchased by a restaurant supplier at some discounted price.
The new price after discount in dollars =
We see that the total cost of 9 ovens which was originally has been decreased to
after discount.
The decrease amount is the discount amount on 9 ovens which is = $180
To find discount offered on each oven, we will again use unitary method.
Discount on 9 ovens = $180
∴ Discount on 1 oven =
∴ Each oven is discounted by $20.
