Answer:
6
Step-by-step explanation:
All triangles equal 180 degrees to this is what I did:
8x + 2 + 70 + 60 = 180
8x + 2 + 130 = 180
8x + 132 = 180
subtract 132 from each side
8x = 48
now divide each side by 8 to isolate the x
x = 6.
Answer: 0
Step-by-step explanation:
Since m is with x, you don't need to care about y
We would get 2x - 6x + 4x = mx
0x = mx
m is 0
Correct option is A. Dime novels, known in nineteenth-century England
as "penny dreadfuls," flourished because increased mechanization of printing and increased literacy rates made production of large numbers of these books profitable.
The sentence is correct as is: it has a sound structure with no grammatical errors. "Increased mechanization" corresponds with "increased literacy rates" thus maintaining the structure of the sentence. A is the best answer.

Answer:
see explanation
Step-by-step explanation:
(a)
OC = OB ( both radii of the circle )
Thus Δ BOC is isosceles with congruent base angles.
∠ BOC = ∠ BCO = 50°
(b)
∠ ACB = 90° ( angle in a semicircle ), then
∠ ACO = 90° - 50° = 40°
OA = OC ( both radii of the circle )
Thus Δ ACO is isosceles with congruent base angles.
∠ BAC = ∠ ACO = 40°
