Answer:

8.4cm

Step-by-step explanation:

first you have to square both sides

8²+4²= Hypotenuse (the diagonal)

you'll get

56 + 16

next you add it, and it'll equal 72

lastly you'll find the square root of that number

which is going to give you 8.4

In a circuit, two resistors of 100 Ω and 80 Ω are connected in parallel. The parallel group is then connected in series with a 1
nordsb [41]

Answer:

Total Resistance = \frac{1300}{9} Ω  (or 144.44 Ω)

Step-by-step explanation:

If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:

\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}

If 2 resistors with resistance x and y and connected in series, their total resistance would be:

Total = x + y

<em>Now, the first part, 100 and 80 are in parallel, so according to formula it would be:</em>

<em>\frac{1}{Total}=\frac{1}{x}+\frac{1}{y}\\\frac{1}{Total}=\frac{1}{100}+\frac{1}{80}\\\frac{1}{Total}=\frac{9}{400}\\Total = \frac{400}{9}</em>

<em />

<em>Now, this is connected in series with 100, so the grand total would be:</em>

<em>Total Resistance of Circuit = \frac{400}{9}+100=\frac{1300}{9}</em>

<em />

This is the total resistance of the circuit.

Same side, interior angles of parallel lines cut by a transversal are supplementary.
The sum of the measures of supplementary angles is 180.

Angles 4 and 6 are same side, interior angles, so their measures add to 180.

m<4 + m<6 = 180

109 + m<6 = 180

m<6 = 180 - 109

m<6 = 71

Answer: m<6 = 71 deg.
