Angle 1 is congruent to angles 3, 5, and 7. We know this because vertical angles are congruent (angle 3), as are corresponding angles (angle 5) and alternate exterior angles (angle 7).

Angle 3 is congruent to angles 1, 5, and 7. We know this because vertical angles are congruent (angle 1), as are corresponding angles (angle 7) and alternate interior angles (angle 5).

Angle 4 is congruent to angles 2, 6, and 8. We know this because vertical angles are congruent (angle 2), as are corresponding angles (angle 8) and alternate interior angles (angle 6).

What is the slope??????
nikitadnepr [17]

Answer: The slope is 1/4.

Step-by-step explanation:

To find the slope, find two points on the line and find the difference in their y coordinates and divide it by the difference in their x coordinates .

(0,20)  and   (40,30)  

Difference in y: 30 - 20 = 10  

Difference in x:  40 - 0 = 40  

Slope:  10/ 40 = 1/4

Ty received test grades of 82%, 74%, 76%, 76%, and 74%.
Nikitich [7]

Answer:

a) To earn C he needs at least 68 and less than 98

b) No, he couldn't make it.

Step-by-step explanation:

I. His avg value is (382 + x)/6

 I pick a random number and that gave

 (68 => to reach 75) and (98 => to reach 80)  

So that makes he needs at least 68 and less than 98

II. The reason why he cannot make it is

 if 100 is 100%

      =   (100 + 382)/6

      = 80.33 That's impossible to reach 90

Hope that help :)
