Answer:
Angle 1 = 35
Angle 2 = 70
Angle 3 = 75
Step-by-step explanation:
Let's define Angle 1 as <em>x</em>
<em />
Angle 1 = x
Angle 2 = 2x
Angle 3 = 2x + 5
x + 2x +2x + 5 = 180
5x + 5 = 180
5x = 175
x = 35
Angle 1 = 35
Angle 2 = 70
Angle 3 = 75
All the equations can be graphed and solved by graphing. They can also be solved using various other methods
Its B
rise over run dictates that its 2/8 which simplifies to 1/4
and its at an upward angle from left to right therefore its positive.
Slope is rise/run
to find it we do (y1-y2)/(x1-x2)
y1 means the 1st y and y2 means the second y
in (x,y) form
y1=4
y2=4
x1=10
x2=7
(4-4)/(10-7)=0/3=0
slope is 0
