Supplementary angles are angles that together, for an angle of 180°. Straight lines are also 180°, so what you need to look for in this exercise are angles, next to eachother, on the same straight line.
those are:
1,2
1,4
2,3
5,6
5,8
6,7
7,8
3,4
so the right answers are option 1 and 2
Answer:
Step-by-step explanation:
Surface area is the area times all the faces
Answer:
Neither
Explanation:
The slope-intercept form of the equation of a line is generally given as;

where m = the slope of the line
b = the y-intercept of the line
Two lines are said to be parallel if they have the same slope. Looking at the two given equations below, we see that the slope of the 1st one, 5/7, is different from the slope of the 2nd one, 7/5;

Two lines are said to be perpendicular if their slopes are negative reciprocals of each other, let's go ahead and compare their slopes;

So the two lines are not perpendicular to each other. It, therefore, means that the correct answer will be Neither.
Answer:
72
Step-by-step explanation:
you multiply the length and the width
Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
