Answer:
6) 40°
7) 65°
8) 65°
Step-by-step explanation:
6) Total angle in a triangle is 180
180-70-70 = 40
7) y + 55 + 60 = 180
y = 65
8) 50 + n + n = 180
50 + 2n = 180
2n = 180 - 50
2n = 130
n = 130/2 = 65
If line BC is congruent to line BD then angles C and D are also congruent
so you would set up the problem to find <em>x </em>as:
5x-19=2x+14
+19 +19
____________
5x=2x+33
-2 -2
_____________
3/3x=33/3
____________
x=11
Just pug in x to the equations to solve the rest

Step-by-step explanation:
Part B was solved using a graphing calculator
The slope of the line is 2.
<u>Step-by-step explanation:</u>
The given points are (5,-3) , (6,-1) , (7,1) , (8,3).
To find the slope of the line that contain these points is calculated by the slope formula.
Slope = 
Take any two points from the given set of points.
Let,
(x1,y1) = (5,-3)
(x2,y2) = (6,-1)
Slope =
⇒ 2
Therefore, the slope of the line is 2.
Similarly, the slope of the line can be known by using any two points on the line in the slope formula.
1,111 im pretty sure because 1 to the power of 1 times to the power of 1 is 1
