Answer:

x=3

Step-by-step explanation:

Hi there!

We are given ΔRTS, m<T=25x, m<S=57+x (both inside triangle RTS), and m<TRQ (outside of ΔRTS)=45x

We want to solve for x.

We can use the exterior angle theorem, which states that a measure of an exterior angle (an angle outside of a triangle) is equal to the sum of two remote interior angles (adding the values of two different angles that are inside the triangle gives us the value of the angle outside of a triangle).

Based on the theorem, this is true:

m<T+ m<S= m<RTQ

We can plug in values we know into the equation to get:

25x+57+x=45x

Now combine like terms

26x+57=45x

Subtract 26 from both sides

57=19x

Divide both sides by 19

3=x

Hope this helps!

Using the sine rule, calculate the length y. Give your answer to 2 s.f.​
Tpy6a [65]

Answer:

y = 9.84 mm

Step-by-step explanation:

<h2>Sine rule:</h2>

Law of sine:

   \sf \boxed{\bf \dfrac{a}{Sin \ A}=\dfrac{b}{Sin \ B}= \dfrac{c}{Sin \ C}}

    a = y

    A = 31°

   b  = 17 mm

    B = 117°

\sf \dfrac{y}{Sin \ 31^\circ}=\dfrac{17}{Sin \ 117^\circ}\\\\

          \sf y = \dfrac{17}{Sin \ 117^\circ}*Sin \ 31^\circ\\\\  y = \dfrac{17}{0.89}*0.515\\\\y = 9.84 \ mm

when a relation is drawn on an xy-plane what is another name for the set of all x values from its graph?
Galina-37 [17]

Another name for the set of all x-values for a relation is: domain.

<h3>What is the Domain of a Relation?</h3>

The domain of a relation can be defined as all the x-values that corresponds to the y-values that are plotted on a graph.

They are referred to as the input or the domain of the relation. Therefore, another name for the set of all x-values plotted for a relation on a graph is: domain.

Dany has a business selling bracelets for 7.50 each. She only has enough material to make 5 bracelets. If x represents the numbe
ziro4ka [17]

Answer:

The range is [0,37.5]

Step-by-step explanation:

We start by writing the equation that links x and y

From the question;

y = 7.5x

Now, she has enough material to make 5 only

When we talk of range, we are referring to the values on the y-axis

So the lowest y value is 0

and since the highest number of bracelets is 5;

The total cost of the 5 is 7.5(5) = 37.5

So the range is [0,37.5]
