The perimeter of the triangle is 42. Find the length of all the sides.
iragen [17]
<h3>Given :-</h3>

  • Perimeter of triangle = 42

  • Side 1 of triangle = (x + 4)

  • Side 2 of triangle = (3x + 8)

  • Side 3 of triangle = (5x + 6)

<h3>To find:-</h3>

  • Length of sides

<h3>Explanation:</h3>

So to find length of sides we have to find the value of x.We can find value of x , by this formula:

\\  \\

\bigstar \boxed{ \rm perimeter \: of \triangle \:  = side_1 + side_2 + side_3}

\\  \\

So:-

\\

\dashrightarrow \tt perimeter \: of \triangle \:  = side_1 + side_2 + side_3 \\

\\  \\

\dashrightarrow \tt 42  = (x + 4) + (3x + 8)+( 5x + 6) \\

\\  \\

\dashrightarrow \tt 42  = x + 4+ 3x + 8+5x + 6 \\

\\  \\

\dashrightarrow \tt 42  = x + 3x+5x+ 4 + 8 + 6 \\

\\  \\

\dashrightarrow \tt 42  = 9x+ 4 + 8 + 6 \\

\\  \\

\dashrightarrow \tt 42  = 9x+ 18\\

\\  \\

\dashrightarrow \tt 42  - 18 = 9x \\

\\  \\

\dashrightarrow \tt 24 = 9x \\

\\  \\

\dashrightarrow \tt  9x = 24 \\

\\  \\

\dashrightarrow \tt  x = \dfrac{24}{9}  \\

\\  \\

\dashrightarrow \bf  x =2.67 \{approx \}\\

\\  \\

  • Side 1 of triangle = (x + 4)
  • Side 1 of triangle =2.67 + 4
  • Side 1 of triangle = 6.67

  • Side 2 of triangle = 3x + 8
  • Side 2 of triangle = 3 × 6.67 + 8
  • Side 2 of triangle = 20.01 + 8
  • Side 2 of triangle = 28.01

  • Side 3 of triangle = 5x + 6
  • Side 3 of triangle = 5 × 2.67 + 6
  • Side 3 of triangle = 13.35 + 6
  • Side 3 of triangle = 19.35

What is another way to write 101 - 13.7x = 73.6
jonny [76]

Answer:

x=2

Step-by-step explanation:

101-13.7x=73.6

13.7x=101-73.6

13.7x=27.4

x=27.4/13.7

x=2

According to records from 50 years, there is a 2/3 chance of June temperatures being above 80 F. Azul needs to find the probabil
Brrunno [24]

Record of june temperature of last 50 years

Probability of June temperature being above 80° F from last 50 years

                      =\frac{2}{3}

It means , out of 30 days ,there are  only 20 days , in which temperature is above 80°F.

⇒Probability that it will be above 80° F for 20 or more days this June

                =\frac{20+x}{30}  

where, x is the number of extra days after 20 days in month of june, when temperature is above 80°F.

Value of this Probability will be in between

                \frac{2}{3}\leq P \leq 1  

Now, what Azul wants

 To find the probability that it will be above 80° F for 20 or more days this June.

The Simulation given is

  ⇒There are 30 days in June. If we use a number cube with the numbers 1-6 and assign 1-4 as a temperature above 80° F and 5-6 as a temperature 80° F or below.

Total number of numbers on number cube ={1,2,3,4,5,6}

Favorable Outcome={1,2,3,4}=Temperature above 80° F

Temperature 80° F or below ={5,6}

⇒Probability of getting number {1,2,3,4} on the number cube when rolled once,that is Temperature above 80° F

        =\frac{4}{6}\\\\=\frac{2}{3}

⇒Probability of getting number {5,6} on the number cube when rolled once, that is Temperature 80° F or below

        =\frac{2}{6}\\\\=\frac{1}{3}

This is Incorrect Simulation, as there are chances that , there can be more than 20 days out of 30 days when Temperature goes above 80° F.But Here we have got Probability of temperature being above 80° F for 20 days only, not more than 20 days, which is =\frac{2}{3}

Not,a number

    \frac{2}{3}< \text{Probability} \leq 1.

In the diagram below, if &lt; A = 97 °, &lt; B = 46 °, &lt; D = 97 ° and &lt; F = 37 °, we can say that
sdas [7]

Answer:

  (a)  The two triangles are similar by AA

Step-by-step explanation:

Similar triangles have congruent corresponding angles and proportional corresponding side lengths.

<h3>Third angle</h3>

The third angle in triangle ABC is found using the fact that the sum of angles is 180°.

  ∠C = 180° -∠A -∠B

  ∠C = 180° -97° -46° = 37°

Two of the angles, A and C, match the measures of two of the angles in triangle DEF. The matches are ...

  ∠A = ∠D = 97°

  ∠C = ∠F = 37°

The two triangles are similar by AA.

__

<em>Additional comment</em>

The similarity statement can be ΔABC ~ ΔDEF.
