Can somebody help me ASAP. I attached a picture.

Answer:

Step-by-step explanation:

cot(2x) = 1/(tan(2x))

csc(x) = 1/(sin(x))

cot(2x)/csc(x) = sin(x)/tan(2x)

As x --> 0 this fraction is 0/0 which is an indeterminate form.

Using L'Hopital

Derivatives:

sin(x) ---> cos(x)

tan(2x) ---> 2sec²(2x)

cos(x)/(2sec²(2x))

= ½ as x --> 0

the points (3, 9) and (-3, -9) ate plotted on the coordinate plane using the equation y=a . x ... - did

slava [35]

See the explanation

<h2>Explanation:</h2><h2></h2>

Here we have the following points:

$(3,9) \ and \ (-3,-9)$

The point-slope form of the equation of a line is:

$y=ax+b \\ \\ \\ a:Slope \\ \\ b:y-intercept$

So the slope can be found as:

$a=\frac{-9-9}{-3-3} \\ \\ a=\frac{-18}{-6} \\ \\ a=3$

So:

$y=3x+b \\ \\ \\ Finding \ b: \\ \\ For \ x=3, \ y=9: \\ \\ \\ So: \\ \\ 9=3(3)+b \\ \\ b=9-9 \\ \\ b=0$

So the equation is finally:

$y=3x$

This line passes through and is shown below.

In the figure below, ZAPE and ZEPD are congruent.

Taya2010 [7]

Answer:

54degrees

Step-by-step explanation:

From the given diagram;

2<P + 136 + 74 + 42 = 360 (sum of angle at a point is 360degrees)

2<P +252 = 360

2<P = 360 - 252

2<P = 108

<P = 108/2

<P = 54

Hence the measure of <P is 54degrees

Which statement is true about ∠BPD?

nalin [4]

Option C:

∠BPD congruent to ∠APC.

Solution:

To find which statement is true about ∠BPD.

Option A: It is adjacent to ∠APC.

∠BPD adjacent to ∠APD and ∠BPC.

So, it is not adjacent to ∠APC.

Hence it is false statement.

Option B: It is complementary to ∠BPC.

<em>In a straight line adjacent angles are supplementary.</em>

In straight line CD, ∠BPC + ∠BPD = 180°.

So, ∠BPD is supplementary to ∠BPC.

Hence it is false statement.

Option C: It is congruent to ∠APC.

∠APC and ∠BPD are vertically opposite angles.

<em>If two lines are intersect, then vertically opposite angles are congruent.</em>

So, ∠BPD ≅ ∠APC.

Hence it is true statement.

Option D: It is linear to ∠APC.

∠APC and ∠BPD are not adjacent angles.

So they did not form a linear pair.

Hence it is false statement.

Therefore, option C is the correct answer.

∠BPD congruent to ∠APC.
