the length of side of a triangle are in ratio 2:3:4 and it perimeter is 144 cm find the area of the triangle and the height corresponding to longest side​

Answer»

Solution :

\bf{\red{\underline{\underline{\bf{Given\::}}}}}

The length of side of a triangle are in the ratio 2:3:4 and it perimeter is 144 cm.

\bf{\red{\underline{\underline{\bf{To\:find\::}}}}}

The AREA of the triangle and the height CORRESPONDING to longest side.

\bf{\red{\underline{\underline{\bf{Explanation\::}}}}}

Let the ratio be r

The sides of the triangle :

  • 2r
  • 3r
  • 4r

We know that formula of the perimeter of triangle :

\mapsto\sf{\orange{Perimeter\:of\:triangle=Side+Side+Side}}\\\\\mapsto\sf{144cm=2r+3r+4r}\\\\\mapsto\sf{144cm=9r}\\\\\mapsto\sf{r=\cancel{\dfrac{144}{9}} }cm\\\\\mapsto\sf{\pink{r=16\:cm}}

Now;

  • 1ST side = 2(16) = 32 cm
  • 2nd side = 3(16) = 48 cm
  • 3rd side = 4(16) = 64 cm

\dag\bf{\underline{\underline{\bf{Using\:Heron's\:Formula\::}}}}}

\mapsto\sf{\orange{Sem-perimeter=\dfrac{a+b+c}{2} }}\\\\\\\mapsto\sf{Semi-perimeter=\dfrac{32cm+48cm+64cm}{2} }\\\\\\\mapsto\sf{Semi-perimeter=\cancel{\dfrac{144}{2}} cm}\\\\\\\mapsto\sf{\pink{Semi-perimeter=72cm}}

So;

\mapsto\sf{Area\:_{triangle}=\sqrt{s(s-a)(s-b)(s-c)} }\\\\\mapsto\sf{Area\:_{triangle}=\sqrt{72(72-32)(72-48)(72-64)}}\\ \\\mapsto\sf{Area\:_{triangle}=\sqrt{72(40)(24)(8)} }\\\\\mapsto\sf{Area\:_{traingle}=\sqrt{552960} cm^{2} }\\\\\mapsto\sf{\pink{Area\:_{triangle}=743.61\:cm^{2} }}

Now;

\leadsto\sf{\orange{Area\:of\:triangle=\frac{1}{2} \times base\times height}}\\\\\\\leadsto\sf{743.61cm^{2} =\dfrac{1}{\cancel{2}} \times \cancel{64}cm\times h}\\\\\\\leadsto\sf{743.61\:cm^{2} =32\times h}\\\\\\\leadsto\sf{h=\cancel{\dfrac{743.61cm^{2} }{32cm} }}\\\\\\\leadsto\sf{\pink{h=23.23\:cm}}

Can we multiply a whole row or column of a matrix by minus (-) sign as a form of Elementary Operations ?

Answer»
9.

Find the area of the shaded square.... with solution.​

Answer»

Answer:

90.25

Step-by-step explanation:

You have to USE trigonometry for this.

In the upper Big TRIANGLE ABC right angled at B.

tan A(the one on the left side) = 15/5 = 3

tan A = 3

A = 72 degrees

C = 18 degrees

In the smaller triangle on the right top DEC right angled at E

Angle C = 18 degrees

sin C = DE/DC

sin 18 = DE/DC

0.3 = DE/5

DE = 1.5 units

WE can assume that all small triangles are congruent.

EC = 4.8(Using pythagoras theorem)

The four lines which are intercepting to create the SQUARE are equal to 5* root(10).( Using pythagoras theorem for the bigger triangles.)

DE is the small PART of the big line .

Similarly the other part is equal to EC since the triangles are congruent.

Therefore,

side of smaller square = 5 root(10) - (1.5 + 4.8)

side of smaller square = 15.8 - 6.3

side of smaller square = 9.5

area of smaller square = side^2 = 9.5^2 = 90.25 sq.units

Step-by-step EXPLANATION:

ADJUSTING the CUBIC polynomial in TERMS of divisor

we have

2X³-7X²+7X-2

= (2X³-6X²+4) - ( X²-3X+2) +4X-4

= 2X( X²-3X+2) -1(X²-3X+2)+4(X-1)

= (X²--3X+2)(2X-1) +4(X-1)

= P×Q+R

Subtract 23x2yz+(-35x2yz) from1/2x2yz​

Answer»

The '−' sign can be used multiple times as REQUIRED: for example, 8 − 2 − 2 = 4.

This calculation is correct, but it can be simplified by adding together the numbers we are subtracting.  In our example, 8 − 2 − 2 = 4 can be simplified to 8 − 4 = 4 (the two 2s have been added together to GIVE 4, which is then SUBTRACTED from 8).

Solve this ................​

Answer»

Question :

  • In an equilateral triangle with SIDE a , PROVE that area = √3a²/4

To Prove :

  • Area of equilateral triangle = √3a²/4

Proof :

FIRST CHECK attachment

By using Pythagoras theorem

\tt \implies{a}^{2}  =  {h}^{2}  +   {  \bigg(\frac{a}{2}  \bigg)}^{2}  \\  \\\implies  \tt {a}^{2}  =  {h}^{2}  +  \frac{ {a}^{2} }{4}  \\  \\   \tt \implies {h}^{2} = {a}^{2}  -  \frac{ {a}^{2} }{4}  \\  \\ \implies \tt  {h}^{2}  =  \frac{ {4a}^{2 } -   {a}^{2}  }{4}  \\  \\\implies  \tt  {h}^{2}  =  \frac{3 {a}^{2} }{4}  \\  \\\implies \tt h =  \sqrt { \frac{3 {a}^{2} }{4} }  \\  \\ \implies\tt h =  \frac{ \sqrt{3} a}{2}

Now

\large\boxed{ \tt Area_{triangle} =  \frac{1}{2}  \times b \times h} \\  \\   \tt \implies \frac{1}{2} \times a \times   \frac{ \sqrt{3} a}{2}   \\  \\ \tt \implies \frac{ \sqrt{3} {a}^{2}  }{4}

Hence Proved

6. Find the mean of the data =2/3,5/3,1/3,5/6,1/6​

Answer»

Mean of the DATA is 18.33.

Step-by-step EXPLANATION:

We are given the following data below ;

2/3, 5/3, 1/3, 5/6, 1/6​

Now, as we know that formula for finding mean for any discrete data is given by;

                              Mean, \bar X  =  \frac{\sum X}{n}

where, \sum X  = Sum of all the OBSERVATIONS in data

                n  = number of observations

Here, the obs. are :  \frac{2}{3} ,\frac{5}{3} ,\frac{1}{3} ,\frac{5}{6} ,\frac{1}{6}

Firstly, we will try to make the DENOMINATOR same for all the given FRACTION values, that is;

                       \frac{2}{3} = \frac{2 \times 2}{3 \times 2} =\frac{4}{6}

                       \frac{5}{3} = \frac{5 \times 2}{3 \times 2} =\frac{10}{6}    

                       \frac{1}{3} = \frac{1 \times 2}{3 \times 2} =\frac{2}{6}

                       \frac{5}{6} = \frac{5 \times 1}{6 \times 1} =\frac{5}{6}

                       \frac{1}{6} = \frac{1 \times 1}{6 \times 1} =\frac{1}{6}

Now, Mean of the data, \bar X  =  \frac{\frac{4}{6}+\frac{10}{6}+\frac{2}{6}+\frac{5}{6}+\frac{1}{6} }{5}

                                             =  \frac{22}{6}\times 5  =  18.33

Hence, the mean of the given data is 18.33.

If the ratio of cylinder of height and radius is 5:7 and the curved surface area is 5500 sq.unit then find its radius and height?

Answer»

ANSWER:

Step-by-step explanation:

Given :-

Ratio of height and radius of cylinder = 5 : 7

Curved Surface Area = 5500 SQ. unit

To Find :-

Radius and Height

Formula to be used :-

Curved Surface Area = 2πrh

Solution :-

Putting all the values, we get

2πrh = 5500

⇒  2 × 3.14 × 5x × 7x = 5500

220 x²= 5500

⇒  x² = 25

X = 5

Now, Radius and Height

Radius of cylinder = 5x = 5(5) = 25 cm

Height of cylinder = 7x = 7(5) = 35 cm

Hence, The radius and height of cylinder are 25 cm and 35 cm.
