Answer:
The new price is 66% off the original not 75% off
Step-by-step explanation:
Let x be the original price
First take 60 percent off
x - x*60% = new price
x- .60x = .40x
The new price is .40x
Then take 15 % off
(.40x) - (.40x)*15%
.40x - .40x*.15
.40x - .06x
.34x
100 -.34 =.66
The new price is 66% off the original not 75% off
Let
x--------> the measure of the adjacent interior angle
y--------> the measure of an exterior angle at the vertex of a polygon
we know that
The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles
so
°
<u>Examples</u>
case 1)
<u>In a square</u>
°
so
°

In this case
The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle
case 2)
<u>an equilateral triangle</u>
°
so
°

In this case
The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle
therefore
<u>the answer is</u>
sometimes

Lets do this step by step.
This is the trigonometric form of a complex number where
is the modulus and
is the angle created on the complex plane.

The modulus of a complex number is the distance from the origin on the complex plane.
where 
Substitute the actual values of a = -5 and b = -5.

Now Find
.
Raise - 5 to the power of 2.

Raise - 5 to the power of 2.

Add 25 and 25.

Rewrite 50 as 5^2 . 2 .

Pull terms out from under the radical.

The angle of the point on the complex plane is the inverse tangent of the complex portion over the real portion.

Since inverse tangent of
produces an angle in the third quadrant, the value of the angle is
.

Substitute the values of
and
.
