So, first, we know that the whole angle must equal 90 because there's a right angle symbol, and right angles equal 90 degrees.

So, 43 + x + 3 must equal 90.

Or, 46 + x = 90

Then subtract 46 from both sides.

x = 90 - 46

x = 44

These would also be adjacent angles because they share the same vertex.

The sample size suggested by this statement is 664 option second is correct.

<h3>What is the margin of error(MOE)?</h3>

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

\rm MOE = Z\times \dfrac{s}{\sqrt{n}}

Where   Z is the z-score at the confidence interval

            s is the standard deviation

            n is the number of samples.

At 99% confidence Z = 2.576

By using the MOE formula:

0.05 = 2.376×√(0.5(0.5)/n)

After calculating

n = 663.57 ≈ 664

Thus, the sample size suggested by this statement is 664 option second is correct.

In the adjoining figure, area of trangle ABC is
Zepler [3.9K]

Answer:

PQ=4\ cm

Step-by-step explanation:

see the attached figure with the letter D to better understand the problem

we know that

The segment side AD is the height of triangle ABC

so

Triangles PBQ and ABD are similar by AA Similarity Theorem

The area of triangle ABC is equal to

A=\frac{1}{2}(BC)(AD)

we have

A=48\ cm^2\\BC=12\ cm

substitute

48=\frac{1}{2}(12)(AD)

AD=8\ cm

Remember that

If two triangles are similar  then the ratio of its corresponding sides is proportional

so

\frac{BP}{AB}=\frac{PQ}{AD}

substitute the given values

\frac{BP}{2BP}=\frac{PQ}{8}

\frac{1}{2}=\frac{PQ}{8}

PQ=4\ cm
