Answer:

Step-by-step explanation:

Given: ABCD is a parallelogram

To prove: ∠A and ∠B are supplementary,∠B and ∠C are supplementary.

Proof:

Statement                                                             Reason

1. Quadrilateral ABCD is a parallelogram         Given

2. AB||DC and AD||BC               Opposite sides of parallelogram are parallel

3. ∠A and ∠B are same side interior angles

and ∠B and ∠C are same side interior angles.  Definition of parallelogram

4. m∠A+m∠B=180°

and m∠B+m∠C=180°         Same side angles of a parallelogram are of 180°

5. ∠A and ∠B are supplementary.

and ∠B and ∠C are supplementary.    Definition of supplementary angles.

Which of the following represents the factorization of the trinomial below?<br>x2 - 6x +9​
valentinak56 [21]

For this case we must factor the following expression:

x ^ 2-6x + 9

We must find two numbers that, when multiplied, result in 9 and when added, result in -6.

These numbers are -3 and -3.

-3-3 = -6\\-3 * -3 = + 9

Then, the factored expression is of the form:

(x-3) (x-3) = (x-3) ^ 2

Thus, the correct option is option C.

Can someone please help me I’ve tried so many ways and still can’t get the answer.
mr Goodwill [35]

Answer:

15.22

Step-by-step explanation:

The equation of the circumference of a circle is 2(pi)r

This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)

so a simple formula is:

arc length in radians X radius

radius = 4 cm

the area that the question wants is the oposite

of the 142 degree section so 360 - 142 = 218

218 degrees *  (pi/180) = 3.80482 rad

3.80482 * 4 = 15.21928 cm

Pls help me solve this question pls show how you got the answer
Thepotemich [5.8K]
C
it appears that there are 7 cubes, so divide the overall volume by the seven cubes, making the volume of each one would 8. Volume is length times with times height so you would find the cube root of eight which is two. This means that each side length is 2 so you would find the area of each side and add them all together. This adds up to equal 120.
Hope this helped!!
