The measures of angles of a triangle are x°, (x -30)°, (x -60)° find the measure of each angle.​

Answer»

ong>Answer:

The angles of a triangle are x,2x,3x.

Sum of angles of the triangle is 180

o

Thus, x+2x+3x=180

o

⟹6x=180

⟹x=

6

180

⟹x=30

As x=30

The angles of the triangle are, 30

o

,60

o

and 90

o

Since, one of the angles of the triangle is 90

o

. It is a right ANGLED triangle.

Since, all the angles of the triangle are different, Hence all the sides of the triangle will be different. Hence, it is a right angled SCALENE triangle.

The perimeter of a triangle is 52 cm . two of its sides are 17 and 18 cm respectively . find the length of the thired side of a triangle . ​

Answer» GIVEN :-

Perimeter of the triangle = 52 cm

First side of the triangle = 17 cm

Second side of the triangle = 18 cm

To Find :-

The length of the third side of a triangle.

Analysis :-

Substitute the given values in the formula of perimeter of a triangle.

Then you can EASILY find the third angle.

Solution :-

By the formula,

\underline{\boxed{\sf Perimeter \ of \ a \ triangle=a+b+<klux>C</klux>}}

Given that,

Side a = 17 cm

Side b = 18 cm

Perimeter = 52 cm

Substituting their values,

52 = 17 + 18 + c

52 = 35 + c

By TRANSPOSING,

c = 52 - 35

c = 17 cm

Therefore, the sides of the triangle are 17 cm, 18 cm and 17 cm.

Find the median 4,5,10,6,7,14,9,5​

Answer»

Given :-

Data \mapsto 4, 5, 10, 6, 7, 14, 9, 5

To find :-

Solution :-

  • Data in ascending order \mapsto 4, 5, 5, 6, 7, 9, 10, 14

  • (n) \mapsto 8

Here n is even,

Formula to be used :-

\sf{Median \: = \: \dfrac{1}{2}[value \: of \: \bigg(\dfrac{n}{2} \bigg) ^{th} \: term + value \: of \: { \bigg(\dfrac{n}{2} + 1} \bigg)^{th} term]} \\ \sf{= \: \dfrac{1}{2}[value \: of \: \bigg(\dfrac{8}{2} \bigg) ^{th} \: term + value \: of \: { \bigg(\dfrac{8}{2} + 1} \bigg)^{th} term]} \\ \\ \sf{= \: \dfrac{1}{2}[value \: of \: 4 ^{th} \: term + value \: of \: 5^{th} term]} \\ \\\sf{= \: \dfrac{1}{2}[6 + 7}] \\ \sf{= \: \dfrac{1}{2}[13}] \\ \sf{ = \frac{13}{2} }

  • Median = 6.5

Know more :-

▪Mode

  • The no. that appears the most is mode.

  • For EG :- 2,4,8,9,0,8,5,8,4,8

  • Here 8 appears the most. So, 8 is the mode.

▪Median

  • If n is odd,
  • \sf{Median~=~(\dfrac{n + 1}{2})^{th~term}}

) Solve: {2n-(7-5n)}/{9n-(4-2n)}=3/7​

Answer» ONG>Answer:

\frac{37}{16}

Step-by-step explanation:

\frac{2n - (7 - 5n)}{9n - (4 - 2n)} = \frac{3}{7}

=> \frac{2n - 7 + 5n}{9n - 4 + 2n} = \frac{3}{7}

=> \frac{7n - 7}{11n - 4} = \frac{3}{7}

= > 33n - 12 = 49n - 49

=> 49n - 33n = 49 - 12

=> 16N = 37

=> N = 37/16

Show that 1944 is not a perfect cube

Answer»

ong>Answer:

A perfect square is a NUMBER that can be expressed as the product of two equal integers.

The only way to accurately CALCULATE if a number is a perfect square is to find the factors. Before we go through the trouble of finding the factors, there is a quick trick you can use to help determine if you NEED even need to do the extra work.

Try these steps first:

A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square.

Obtain the digital root of the number. The digital root essentially is the sum of all of the digits. If you're lost, don't worry, we'll go over each step in more detail below.

All possible numbers that are a perfect square have a digital root of 1, 4, 7, 9.

Let's try it...

Step 1:

What is the last number of 1,944? It is this number: 1944. The answer is 4. Is 4 in the list of numbers that are never perfect squares (2, 3, 7 or 8)?

Answer: NO, 4 is not in the list of numbers that are never perfect squares. Let's continue to the next step.

Step 2:

We now need to obtain the digital root of the number. Here's how you do it:

Split the number up and add each digit together:

1 + 9 + 4 + 4 = 18

If the answer is more than one digit, you would add each digit of the answer together again:

1 + 8 = 9

What is the digital root of number 1,944?

Answer: 9

Step 3:

So now we know the digital root of 1,944 is 9. Is 9 in the list of digital roots that are always a square root (1, 4, 7 or 9)?

Answer: YES, 9 is in the list of digital roots that are always perfect squares. We can conclude that 1,944 could be a perfect square!

Factoring

OK, so now we know that 1,944 could be a perfect square. We have to find the factors of the number to be sure.

Here are all of the factors of 1,944:

1 x 1,9442 x 9723 x 6484 x 4866 x 3248 x 2439 x 21612 x 16218 x 10824 x 8127 x 7236 x 54

Whoa! That is a lot of factors!

We're looking for a factor combination with equal numbers for X and Y (like 3x3) above. Notice there isn't a equal factor combination, that when multiplied together, PRODUCE the number 1,944. That means 1,944 is NOT a perfect square

Find the roots of 2π2 -5π+7=0​

Answer» ONG>Answer: PLEASE BRAINLIEST MY ANSWER

x = {5 ± i√31} / 4

Step-by-step explanation:

Q) find the roots of 2π2 -5π+7=0

​ ⇒ Given equation is 2π² - 5π + 7 = 0

put the π = x

∴ 2x² - 5x + 7 = 0

we know the formula for FINDING x from equation ax² + bx + c = 0 is

x = [-b ± √(b²-4ac)] / 2a

∵ a=2, b= -5, c=7

x = {-(-5) ± √[(-5)²-4*2*7]} / 2*2

  = {5 ± √[25-56]} / 4

  = {5 ± √[-31]} / 4

  = {5 ± √[31*(-1)]} / 4

x = {5 ± i√31} / 4
