The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for R2, in terms of

<h2>Answer:</h2>

$R_2$ is 3 ohms

<h2>Step-by-step explanation:</h2>

In a circuit containing two resistors $R_1$ and $R_2$ connected together in parallel, the total resistance $R_T$ is given by;

$\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2}$ ---------(i)

<em>Make </em> $R_2$ <em> subject of the formula;</em>

=> $\frac{1}{R_2} = \frac{1}{R_T} - \frac{1}{R_1}$

=> $\frac{1}{R_2} = \frac{R_1 - R_T}{R_TR_1}$

=> ${R_2} = \frac{R_TR_1}{R_1 - R_T}$ ---------------(ii)

From the question,

$R_1$ = 6Ω

$R_T$ = 2Ω

Substitute these values into equation (ii) as follows;

=> ${R_2} = \frac{2*6}{6 - 2}$

${R_2} = \frac{12}{4}$

$R_2$ = 3Ω

Therefore, the value of $R_2$ = 3 ohms or $R_2$ = 3Ω

X/-9 =3<br>I dont understand this.

STatiana [176]

Final Answer: $x = -27$

Steps/Equations:

Question: $\frac{x}{-9} = 3$

Step 1: Move the negative sign to the left side.

$-\frac{x}{9} = 3$

Step 2: Multiply both sides by $3$ .

$-x = 3 * 9$

Step 3: Simplify $3 * 9$ to $27$ .

$-x = 27$

Step 4: Multiply both sides by $-1$ .

$x = -27$

Given: Lines a and b are parallel and line c is a transversal. Prove: Angle2 is supplementary to Angle8 Horizontal and parallel

kondaur [170]

Answer:

The correct option is;

Corresponding angles theorem

Step-by-step explanation:

Type of lines of lines a and b = Horizontal and parallel lines

The transversal to a and b = Line c

The angles between a and c labelled clockwise from the upper left quarter segment = 1, 2, 4 and 3

The angles between b and c labelled clockwise from the upper left segment = 5, 6, 8 and 7

Therefore, we have;

Statement ${}$ Reason

1. a║b, c is a transversal ${}$ Given

2. ∠6 ≅ ∠2 ${}$ Corresponding angles theorem

3. m∠6 = m∠2 ${}$ Definition of congruent

4. ∠6 is supp. to ∠8 ${}$ Definition of linear pair

5. ∠2 is supp. to ∠8 ${}$ Congruent supplement theorem

Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.
