\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
-----------------------------\\\\


\bf \cfrac{sin(48^o)}{32}=\cfrac{sin(B)}{27}\implies\cfrac{27sin(48^o)}{32}=sin(B)
\\\\\\
sin^{-1}\left[ \cfrac{27sin(48^o)}{32} \right]=sin^{-1}[sin(B)]\implies sin^{-1}\left[ \cfrac{27sin(48^o)}{32} \right]=\measuredangle B
\\\\\\
38.83\approx \measuredangle B
\\\\\\
\textit{now, we know angles A and B, angle is C is just 180-A-B}
\\\\\\
\measuredangle C = 180-48-38.83\implies C\approx 93.17^o

so, now we know the ∡C, so, let's use the law of sines to get side "c"

\bf \cfrac{sin(48^o)}{32}=\cfrac{sin(93.17^o)}{c}\implies c=\cfrac{32sin(93.17^o)}{sin(48^o)}

and surely you know how much that is

Determine whether each relation is a function. Give the domain and range for each relation.
brilliants [131]

Answer:

Not a function

Domain: {3,4}

Range: {4,5}

Step-by-step explanation:

A function is a relation where each input has its own output. In other words if the x value has multiple corresponding y values then the relation is not a function

For the relation given {(3, 4), (3, 5), (4, 4), (4, 5)} the x value 3 and 4 have more than one corresponding y value therefore the relation shown is not a function

Now let's find the domain and range.

Domain is the set of x values in a relation.

The x values of the given relation are 3 and 4 so the domain is {3,4}

The range is the set of y values in a relation

The y value of the given relation include 4 and 5

So the range would be {4,5}

Notes:

The values of x and y should be written from least to greatest when writing them out as domain and range.

They should be written inside of brackets

Do not repeat numbers when writing the domain and range

A triangle can be drawn with angle measure of 60 degrees, 60 degrees, and 70 degrees
GrogVix [38]

Answer:

False. All triangles must have a total of 180°. 60° + 60° + 70° = 190°.

What is the product? Two-thirds times eight-ninths StartFraction 10 over 27 EndFraction StartFraction 16 over 27 EndFraction Two
melomori [17]

Answer:

16/27

Step-by-step explanation:

First let's convert this info an equation and then we will solve.

(2/3) * (8/9) = ?

( 2 * 8 ) / ( 3 * 9 ) = ?

( 16 ) / ( 27 ) = ?

16 / 27 = ?

So our fractional answer is 16/27.

In words this would be sixteen over twenty seven.

Cheers.
