The inside angles of a triangle equal 180 degrees
so
(2x -2) + (x+6) + x = 180
combine like terms
4x + 4 = 180
subtract 4 from both sides
4x = 176
divide both sides by 4
x = 44
Now, wherever is says x, plug in 44
(x+6)
44 + 6
angle B is 50
2x - 2
2(44) -2
88-2
Angle A is 86
and the last angle is just 44
To check:
angle a + angle b + angle c =?= 180
86 + 50 + 44 =?= 180
180 = 180
Hope this helps
We know that
slope m=(y2-y1)/(x2-x1)
then
case a) x=18
m=(y2-y1)/(18-18)--------------> is undefined, because <span>the denominator is zero
case b) </span><span>2y-6x=0
2y=6x------------> y=3x
the slope m=3-----------> m is defined
case c) y=9
</span>m=(9-9)/(x2-x1)--------> m=0-----------> m is defined
case d) y=x
m=1---------------> m is defined
the answer is
x=18 has an undefined slope
Answer:
The answer to your question is: first option
Step-by-step explanation:
-x = 5
x = -5
If you would like to know the mean change in elevation per minute, you can calculate this using the following steps:
1200-foot ... 3 minutes
x-foot = ? ... 1 minute
1200 * 1 = 3 * x
1200 = 3 * x
x = 1200 / 3
x = 400-foot
The correct result would be 400-foot per minute.
