2x-10=44+8x
subtract 2x from each side
8x-2x=6x
now we have -10=44+6x
subtract 44 from both sides
-10-44=-54
now we have -54=6x
divide both sides by 6
-54/6=-9
so x=-9
B
The lines are parallel to each other
Answer:
Step-by-step explanation:
In this geometry, the triangles are similar. That means corresponding sides are proportional:
short side/long side = x/10 = 10/25
x = 100/25 = 4 . . . . multiply by 10
__
hypotenuse/short side = y/x = (x+25)/y
y² = 4(29) = 116 . . . . . use 4 for x; cross multiply
y = √116 ≈ 10.8
If you look at the figure, you will see that there is an angle opposite each angle whose value we have. Therefore, just do (3x+2x+x)·2= 6x·2=12x
Now, 360/12=30°
x=30°
Answer:
B
Step-by-step explanation:
C would also be the correct answer but its not rounded to the nearest tenth.
