"Find the measures of two supplementary angles if their measures are 3:7 Since the ratio is 3:7 we can assume that the angles are equal to 3x and 7x?"
3x+7x=180° (180° since a line is equal to that)
then solve
10x=180
x=18
then substitute x=18 in 3x and 7x
3x=54°. 4x=126°
126° and 54°

The graph of which of the following will be parallel to the graph of 4x – 3y = –12? a. y= 4/3x -3/2 b.6x-4y=-8 c. y=3/4x+1 d.4x- 2y=-12

Pls the last one and it has to be like number 6
