Answer:

multiply equation 1by -3 and multiply equation 2 by 1

-3×2x+3y×-3=13×-3

-6x+4y=0

-6x-9y=-39

-6x+4y=0

Step-by-step explanation:

-13y=-39

divide both side by -13

-13y/-13=-39/-13

y=3

put answer of y in equation 1

2x+3y=13

2x+3×3=13

2x+9=13

take like terms of the equation

2x=13-9

2x=4

divide both side by 2

2x/2=4\2

x=2

(x,y)=(2,3)

This diagram of airport runway intersections shows two parallel runways. A taxiway crosses both runways.
ella [17]

The <u><em>correct answer</em></u> is:

They are corresponding angles .

Explanation:

The two parallel runways are cut by the taxiway. This taxiway serves as a transversal.

When two parallel lines are cut by a transversal, corresponding angles are angles that are on the same side of the transversal and in the same relative position compared to the parallel lines.

∠1 and ∠5 are both above the taxiway (transversal). They are also both to the right of their corresponding parallel lines. This makes them corresponding angles.
