<h3>Answer: x = 50</h3>
========================================
Explanation:
The angles shown are vertical angles. Any pair of vertical angles are always congruent (i.e. equal)
Set the two expressions equal to each other and solve for x.
2(x+10) = 3x-30
2x+20 = 3x-30 ... distribute
2x+20-2x = 3x-30-2x ... subtract 2x from both sides
20 = x-30
20+30 = x-30+30 ... add 30 to both sides
50 = x
x = 50
---------
Check:
Plug x = 50 into the equation. Both sides should result in the same value
2(x+10) = 3x-30
2(50+10) = 3*50-30
2(60) = 3*50-30
120 = 150-30
120 = 120
The answer is confirmed.

Please answer,,,
Answer: A. only II
Step-by-step explanation:
Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's the divisible unit.
The number of books and bracelets also discrete, thus the answer is A.
