Answer: x = 2/3
Step-by-step explanation:
<em>Add all sides.</em>
2x-2 + 2x - 2 + x + x =
6x - 4
<em>Put " = 0 "</em>
6x-4 = 0
Add 4 to both sides.
6x-4 = 0
+4 = +4
-------------------
6x=4
You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!
<em></em>
<em>NOW DIVIDE 6 FROM BOTH SIDES</em>
6x = 4
/6 /6
-----------
x= 4/6
<em>SIMPLIFY / REDUCE FRACTION</em>
4/6 divided by 2 = 2/3
2/3 is the answer !
Okay so what we know is that there are 6 sides.
—————-————————————————————
3separate groups have the same measurements. So really 3 groups of 2 that have the same measurements.
—————————————————————
2 sides are 3*2 —————>an area of 6
2 sides are 3*2—————>an area of 6
2 sides are 2*2—————>an area of 4
—————————————————————so, we add those #s up and get 6+6+4 which equals 16 as your answer.
Answer:
cosθ = 
Step-by-step explanation:
tanθ = -(65/72)
If it is in the 2nd quadrant, this means that y is positive but x is negative
tanθ= opposite/adjacent or (y/x)
tanθ=
We know that the adjacent value = -72 and the opposite value = 65
The hypotenuse can be get by the following

cosθ is just adjacent/hypotenuse
Our adjacent value is -72
Our hypotenuse is 97, therefore
cosθ =
