Answer:

The sum of a° and b° will be 180°.

Step-by-step explanation:

We know that two angles are supplementary when they add up to 180 degrees.

We also know that we know that a straight angle is said to be having 180 degrees. A straight angle does change the direction to point the opposite way.

i.e.

Straight angle = 180°

For example, a flat surface does have an angle of 180 degrees. Also, a straight stick does have a straight angle or 180 degree.

So, from the figure, the sum of a° and b° will be 180° as they add up to 180 degrees on a straight line and hence a° and b° are supplementary angles.

Therefore, the sum of a° and b° will be 180°.

lakkis [162]
The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
(3 x^{2}  + 3x - 5) + (-7 x^{2}  + 9)<span>
Use distributive property:
</span>3 x^{2}  + 3x - 5 - 7 x^{2}  + 9
Combine Like Terms:
&#10;-4 x^{2} +3x+4
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!

HELP ASAP HELP PLEASE ASAP
Gnesinka [82]

Answer:

WXYZ can not be a rectangle because consecutive sides are not perpendicular to each other.

Step-by-step explanation:

The given vertices are W(-4,3), X(1,5), Y(3,1) and Z(-2,-1).

Plot these points on coordinate plane and draw the quadrilateral as shown below.

Slope=\dfrac{y_2-y_1}{x_2-x_1}

Using this formula, we get

m_{WX}=\dfrac{5-3}{1-(-4)}=\dfrac{2}{5}

m_{XY}=\dfrac{1-5}{3-1}=\dfrac{-4}{2}=-2

Now,

m_{WX}\times =\dfrac{2}{5}\times (-2)=-\dfrac{4}{5}\neq -1

Here, WX and XY are two consecutive sides of quadrilateral but the product of their slopes is not equal to -1. It means they are not perpendicular to each other.

Since, all interior angles of a rectangle are right angles, therefore, WXYZ can not be a rectangle.
