The percentage decrease is 15%.
180 - 153 = 27 (price decrease)
10% of 180 = 18
5% of 180 = 9
18 (10%) + 9 (5%) = 27 (15%)
The price decreased by 27 and when you convert this into a percentage by dividing by the original price and then multiplying by 100, the result is a 15% decrease in the price.
To calculate the percentage decrease in the price, you first need to find out how much the price has fallen by. So subtract the new price (153) from the old price (180). This gives you 27.
Next, to convert this decrease to a percentage, you divide it by the original price (180) and then multiply by 100. So the calculation would be (27/180)*100 = 15%.
Therefore, the price of the item decreased by 15%.

Answer:C
Step-by-step explanation:
A parallelogram has one angle thatmeasures 76°. The measures of the other three angles in the parallelogram are 76°, 104°, and 104°.
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
A parallelogram has one angle that measures 76°.
We already know that in a parallelogram opposite angles are equal.
1st angle = 76°
Third angle = 76°
And let the other 2nd and 4th angles be x and x
So, The sum of all the angles of quadrilateral
76° + 76° + x + x = 360°
152° + 2x = 360°
2x = 360° - 152°
2x = 208°
Therefore x = 104°
Hence, We have got all angles that are 76°, 76°, 104°, and 104°.

Step-by-step explanation:
We know that in a parallelogram opposite angles are equal so
1st angle = 76°
Third angle = 76°
And let the other 2nd and 4th angles be x and x
Now
76° + 76° + x + x = 360° <being sum of angles of quadrilateral >
152° + 2x = 360°
2x = 360° - 152°
2x = 208°
Therefore x = 104°
We have got all angles
76° , 76° , 104° and 104°
