Answer:

Step-by-step explanation:

∠1 = ∠2 = 70 {Corresponding angles}

2x +2 y = ∠1

2x + 2y = 70 --------------(I)

2x + y = ∠2

2x +y = 70 --------------(II)

Subtract equation (II) from (I)

(I) 2x + 2y = 70

(II) 2x + y = 70

<u>- - - </u> {subtract}

y = 0

Plugin y= 0 in equation(I)

2x + 0 = 70

2x = 70

x = 70/2

x = 35

x = 35 ; y = 0

What is the lim of (((1/x)-(1/2))/x-2) , as x approaches 2

Katyanochek1 [597]

I assume the denominator is $x-2$ .

$\lim_{x\to2}\dfrac{\dfrac{1}{x}-\dfrac{1}{2}}{x-2}=\\
\lim_{x\to2}\dfrac{\dfrac{2}{2x}-\dfrac{x}{2x}}{x-2}=\\
\lim_{x\to2}\dfrac{\dfrac{2-x}{2x}}{x-2}=\\
\lim_{x\to2}\dfrac{2-x}{2x(x-2)}}=\\
\lim_{x\to2}-\dfrac{x-2}{2x(x-2)}}=\\
\lim_{x\to2}-\dfrac{1}{2x}}=\\
-\dfrac{1}{2\cdot2}=\\
-\dfrac{1}{4}=
