largest angle of triangle is twice the sum of other two the sum smallest is 1 by 4 of the largest find the smallest angle​

Answer»

Answer: SMALLEST angle = 30°

Step-by-step explanation:

LET the Largest angle be A, smallest be C and other one be B.

According to the QUESTION,

A=2(B+C) &

C=A/4

We KNOW that, A+B+C =180°

B+C = 180°-A

So, the equations become

A= 2(180°-A) ......(I)

C= A/4. ...... (II)

On solving the (I) one, we get, A= 120°

Use it for the (II) equation and we get, C=30°....

Therefore, smallest angle = 30°

Hoped it helped all....:-)

Answer»

Answer:

\boxed{\sf \dfrac{25 + \sqrt{3}}{22}}

Step-by-step explanation:

GIVEN that ;

\sf  \frac{3}{5 -  \sqrt{3} }  +  \frac{2}{5 +  \sqrt{3} }  \\  \\ \bf Taking  \: LCM :  \\ \\ \implies \sf  \frac{3(5 +  \sqrt{3} ) + 2(5 -  \sqrt{3}) }{(5 -  \sqrt{3} )(5 +  \sqrt{3} )}  \\  \\ \implies \sf  \frac{15 + 3 \sqrt{3}  + 10 - 2 \sqrt{3} }{(5) {}^{2} - ( \sqrt{3}) {}^{2} }  \\  \\ \implies \sf   \frac{25 +  \sqrt{3} }{25 - 3}  \\  \\ \implies \sf   \frac{25 +  \sqrt{3} }{22}

HENCE, the answer is \bf \dfrac{25 + \sqrt{3}}{22}

If a + b is equals to 12 and a b is equal to 27 find the value of a cube plus b cube​

Answer»

Answer:

a³ + b³ = 756

Step-by-step explanation:

a + b = 12 ------(1)

ab = 27 ------(2)

from eq. 1

a + b = 12

a = 12 - b

PUT a in eq. 2

ab = 27

(12 - b)b = 27

12B - b² = 27

b² - 12b + 27 = 0

b² - 9b - 3b + 27 = 0

b(b - 9)*-3(b - 9) = 0

(b - 9)(b - 3) = 0

b = 9 or b = 3

put b in eq. 1

(if, b = 3) a + b = 12

a + 3 = 12

a = 12 - 3

a = 9

(if, b = 9) a + 9 = 12

a = 12 - 9

a = 3

now, a³ + b³ (if a=3 and b=9)

= (3)³ + (9)³

= 27 + 729

= 756

or, if a = 9 and b = 3

then, a³ + b³

= (9)³ + (3)³

= 729 + 27

= 756

so , a³ + b³ = 756

Solve for x and yplease urgent​

Answer»

Step-by-step explanation:

47x + 31y = 63___________(i)

31x + 47y = 15___________(ii)

ADD EQUATION (i) and (ii), we GET

78x + 78y = 78

78(x + y) = 78

x + y = 1_________(iii)

Subtract equation (i) and (ii), we get

16x - 16y = 48

16(x - y) = 48

x - y = 3__________(iv)

Subtract equation (iii) and (iv), we get

2x = 4

x = 2

Put the value of x equation (i)

x + y = 1

2 + y = 1

y = 1 - 2

y = -1

41.

the value of the expression (10y-20) depends on the value of y verify this by giving five different values to y and finding for each y the value of (10y - 20) . from the different values of (10y- 20) you obtain, do you see a solution to 10y -20 =50? if there is no solution, try giving more values to y and find whether the condition 10y-20=50 is met​

10Y -20=50

10y =50+20

10y = 70

y = 70/10

Use a suitable identity and factorise a. x^2/4 - y^2/4 b. x^2=y^2/100​

Answer»

ANSWER:

a.  (x + y)(x - y)/4   and     b.  (10x + y)(10x - y) = 0

Step-by-step EXPLANATION:

a. We know that

      a² - b² = (a - b)(a + b)

So, x²/4 - y²/4 = (x² - y²)/4

                       = (x + y)(x - y)/4

b.    x² = y²/100

      x² - y²/100 = 0

   a² - b² = (a - b)(a + b)    

     (x)² - (y/10 = 0

     (x + y/10)(x - y/10) = 0

     (10x + y)(10x - y)/10 = 0

     (10x + y)(10x - y) = 0*10

     (10x + y)(10x - y) = 0

Find the value of a so that the point (3,a), lies on the line represented by 2x+3y=5.​

Answer»

Step-by-step explanation:

those points are on the LINE MEANS if we PUT that point in the equation, it must satisfy the equation.

and

(x,y),this refers to x co-ordinate and y co-ordinate

respectively

therefore putting x=3 and y=a in the equation,

2(3)+3(a)=5

3(a)=5-6

a=-1/3
