Answer:

a. right angles.

Step-by-step explanation:

Perpendicular lines intersect and form 4 right angles.

When two perpendicular lines intersect, you can assume the shape of '+'

We can see that there are 4 right angles made in this shape.

Moreover a straight line is 180 degrees, when it is divided into two equal parts during perpendicular bisection, two right angles are formed. Similarly two right angles are formed on the other side of the line.

On Monday, during a one day sale, the price of a suit was decreased by 20%. On Tuesday, the price of the suit was changed back t

nignag [31]

Answer:

25%

Step-by-step explanation:

If we consider the original price of the piece of suit is x.

Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.

Therefore, the new price of the suit on Monday is $x( 1 - \frac{20}{100}) = 0.8x$ .

Now, the price of the suit on Tuesday was changed back to the original price i.e. x.

Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.

So, the percentage change in price of the suit on Tuesday is $\frac{0.2x}{0.8x} \times 100 = 25$ %. (Answer)
