Since the lengths of the segments AD=PD are equal that means that the triangle is an isosceles triangle. This also means that the angles A and P (in the triangle) are equal.

This also means that the angle P' (the one inside the quadrilateral) is equal to:

180-\measuredangle B

Now, if we extend the sides DP and CB we notice that the angles P' and Q

are equal

The only way that this angles can be equal is if the line segments DP and CB are parallel, this comes from the fact that two alternate interior angles are equal if and only if the lines are parallel.

Show that sin (x + pi) = -sin x.
Lunna [17]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

sin(A + B) = sin A cos B + cos A sin B

In this problem we have

sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)

Remember that

sin(\pi) = 0

cos(\pi) = -1

substitute

sin(x + \pi) = sin(x)(-1) + cos(x)(0)

sin(x + \pi) = -sin(x)

Which graph shows the solution to this inequality? 3r+2(12r+7) ≤ 5r-8<br>​
Ilya [14]

Answer:

r ≥ -1. it is A because r is greater than or equal to -1.

I am sorry <u>if</u> I got it wrong.

Step-by-step explanation:

3r+2(12r+7) ≤ 5r-8

27r+14 ≤ 5r-8

I subtract 27r and 5r.

22r+14 ≤ -8

I subtract 14 and -8.

22r ≤ -22

Divide 22 on both side.

r ≥ -1
