Because it is the same by the 0 and the 0 represents as a place holder for the 32
Answer:


Step-by-step explanation:
∠1 and ∠2 are vertical angles.
∠1 = ∠2
<u>Part A:</u>
<u></u>
Create an equation and solve for x.
20x + 21 = 30x - 29
Add 29 and -20x on both sides.
20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x
Simplify the equation.
50 = 10x
Divide both sides by 10.
= 
Simplify the equation.
5 = x
Switch sides.
x = 5
<u>Part B:</u>
<u></u>
Let x = 5
20(5) + 21
Distribute.
100 + 21
Add.
= 121
Since both angles are vertical angles, they are equal.
∠1 = 121°
∠2 = 121°
Answer:
Number = 2
Step-by-step explanation:
Let the number be <em>x</em>.
According to the question,
- Number increased by 11 = x+11
- Multiplied by 2 is 26 : (x+11)*2 = 26
Equation will be,
Solving for x,
- 2x+22 = 26
- 2x = 26-22
- 2x = 4
- x = 4/2
- x = 2
Thus,the number is 2.
