I don’t understand ?

vertical 7 and 4

supplementary 5 and 1

1. vertical angles: <2 and <5

2. Supplementary angles: <6 and <2

Step-by-step explanation:

Vertical angles are angles that are opposite to each other

-they will always have the same measure

-examples from the picture: 2 and 5, 6 and 1, 3 and 8, 7 and 4

Supplementary angles are angles that add up to 180

-they will always be able to form a straight line

-examples from the picture: 1 and 5, 6 and 2, 1 and 2, 5 and 6, 3 and 7, 7 and 8, 3 and 4, 8 and 4

i dont know

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
