Answer:

The answer to your question is  r = 3

Step-by-step explanation:

                               2r  - 15 = - 9r + 18

Process

1.- Add 9r in both sides

                              2r + 9r - 15 = - 9r + 18 + 9r

2.- Simplify

                                    11r -15 = 18

3.- Add 15 to both sides

                                   11r - 15 + 15 = 18 + 15

4.- Simplify

                                   11r = 33

5.- Divide both sides by 11

                                   11/11 r = 33/11

6.- Simplify and result

                                   r = 3

Use the drop-down menus to complete the proof. Given that w ∥ x and y is a transversal, we know that ∠1 ≅∠5 by the . Therefore,
ololo11 [35]

Answer:

From the graph attached, we know that \angle 1 \cong \angle 5 by the corresponding angle theorem, this theorem is about all angles that derive form the intersection of one transversal line with a pair of parallels. Specifically, corresponding angles are those which are placed at the same side of the transversal, one interior to parallels, one exterior to parallels, like \angle 1 and \angle 5.

We also know that, by definition of linear pair postulate, \angle 3 and \angle 1 are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.

They are supplementary by the definition of supplementary angles. This definition states that angles which sum 180° are supplementary, and we found that \angle 3 and \angle 1 together are 180°, because they are on a straight angle. That is, m \angle 3 + m \angle 1 = 180\°

If we substitute \angle 5 for \angle 1, we have m \angle 3 + m \angle 5 = 180\°, which means that \angle 3 and \angle 5 are also supplementary by definition.
