Tell me which lines are parallel to each other 1. -6x+y=8; 2. y=4; 3. y=3x; 4. y=3

Lines two and four.

Step-by-step explanation:

Parallel lines are known to never intersect. option 2 () is just a horizontal line. The same thing could be said for option 4. See the attachment below. Hope this was helpful.

add an image, and i will answer

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
