A cyclic quadrilateral is a quadrilateral inscribed in a circle

The measure of angle A is 106

<h3>How to determine the measure of angle A</h3>

From the question, we have:

<C= 74

Opposite angles of a cyclic quadrilateral add up to 180.

So, we have:

<A + <C = 180

This gives

<A + 74 =180

Subtract 74 from both sides

<A =106

Hence, the measure of angle A is 106

Answer:

Triangle small ABC

Triangle big DEF

AB = 8 cm , BC = 12 cm , DE = 20 cm , EF = x

So;

$\frac{AB}{DE} = \frac{BC}{EF} \\ \\ \frac{8}{20} = \frac{12}{x} \\ \\ 8x = 12 \times 20 \\ 8x = 240 \\ \\ x = \frac{240}{8} \\ \\ x = 30 cm$

I hope I helped you^_^

Express 14.63 as a mixed number

ivolga24 [154]

14 will be your whole number and your fraction would be 63/100, so the entire thing as a mixed number is 14 63/100

<u>Answer-</u>

<em>A. Brandon’s sound intensity level is 1/4th as compared to Ahmad’s.</em>

<u>Solution-</u>

Given that, loudness measured in dB is

$L=10\log \frac{I}{I_0}$

Where,

I = Sound intensity,

I₀ = 10⁻¹² and is the least intense sound a human ear can hear

Given in the question,

I₁ = Intensity at Brandon's = 10⁻¹⁰

I₂ = Intensity at Ahmad's = 10⁻⁴

Then,

$L_1=10\log \frac{I_1}{I_0}=10\log \frac{10^{-10}}{10^{-12}}=10\log \frac{1}{10^{-2}}=10\log 10^{2}=2\times10\log 10=20$

$L_2=10\log \frac{I_2}{I_0}=10\log \frac{10^{-4}}{10^{-12}}=10\log \frac{1}{10^{-8}}=10\log 10^{8}=8\times10\log 10=80$

$\therefore \frac{L_1}{L_2} =\frac{20}{80} =\frac{1}{4}$
