Find the largest 7 digit number which is perfect square. find the square root of the number?​

Answer»

ANSWER:

The greatest 7 DIGIT no. is 9999999

Step-by-step explanation:

when we take square root of 9999999 we get 3162.27

which mean the required no. is 3162.

Because we can't take GREATER than 3162.

If we take square of 3162

= 3162×3162

The angles of a triangle are in the ratio 2:3 : 4. The largest angle of thetriangle is(a) 120°(b) 100°(c) 80°(d) 60°​

Answer»

Answer:

AnswEr :

The LARGEST angle of the triangle is 80° (option C) .

⠀━━━━━━━━━━━━━

GiveN :

Angles of the triangle are in the ratio 2 : 3 : 4

To FinD :

Largest angle of the triangle = ?

SoluTion :

Let's ASSUME the VALUES of angles as,

∠A = 2x

∠B = 3x

∠C = 4X

⠀━━━━━━━━━━━━━

Now, We know that the sum of all the angles of a triangle is 180°(Angle sum property).

So, in any ΔABC

∠A + ∠B + ∠C = 180°

Substituting the values as PER our assumption,

➠ 2x + 3x + 4x = 180°

➠ 9x = 180°

➠ x = 180°/9

➠ x = 20°

⠀━━━━━━━━━━━━━

★ So, the angles are :

∠A = 2x = 2(20) = 40°

∠B = 3x = 3(20) = 60°

∠C = 4x = 4(20) = 80°

∴ The largest angle is 80°

Hope it helps.

Find the LCM and HCF of 225,200,115

Answer»

Answer:

LCM IS 41400

Step-by-step EXPLANATION:

For Find the LCM of 225, 200, 115

We do prime factors of these numbers

225= 3×3×5×5

200= 2×2×2×5×5

115= 5×23

Look at the factors. 5 (in bold) is COMMON in 225, 200, 115.

So, Take only 5 once and MULTIPLY others.

= 5 × 3×3×5×2×2×2×23

= 41400

The two nmbrs which are plus with each other and give answer 7 but if they are multiply with each other they give answer 450

Answer»

Answer:

Here is your answer_________

Step-by-step explanation:

LET the numbers be X and y

so,

x + y = 7 equation 1

xy = 450 equation 2

for equation 1

x = 7 - y

putting the value of x in equation 2

》》》(7 - y ) y = 450

》》》 7y - y ^2 = 450

》》》 y ^2 - 7y + 450 = 0

》》》 y^2 - 25y + 18 y + 450 = 0

That is y = 25 , - 18

If A B And C are angles of a triangle then show that sin(A+B)= sinC

Answer»

Step-by-step EXPLANATION:

A, B and C are the angles of a TRIANGLE.

Then,

<A+<B+<C=180°(Angle Sum property)

=><A+<B=180°-<C

=>Sin(<A+<B) =Sin(180°-<C) {Taking sin on both sides)

=>Sin(A+B) =SinC (Sin(180°-theta=Sin THETA).

Hiw many silver coins of 1.75 cm diameter and of 2 mm thikness is melted to form of cuboid of dimemsions 5.5 cm×10cm×3.5 cm.?

Answer»

Step-by-step explanation:

Let the no. of COINS be 'X'.

DIAMETER of the coins =1.75cm

Radius=1.75/2cm

Thickness of each coin=2mm=0.2cm=h.

Dimensions of the CUBOID are=5.5cm×10cm×3.5cm.

A.to.q

Vol.of the cuboid =Vol.of 'X' coins

=>l×b×h=(X)πr^2h

=>5.5×10×3.5=(X)×22/7×1.75/2×1.75/2×0.2

=>55/10×10×35/10=(X)77/160

=>55×35/10×160/77=(X)

=>400=(X)

THEREFORE 400coins WOULD be formed.

Find the value of x and y in each figures (ii)​

Answer»

HERE IS UR ANSWER DEAR,

in the triangle ,WHOSE ANGLES were

  • 90°
  • ×°
  • 30°

by taking that triangle ,

sum of all the angles in a triangle = 180°

x°+90°+30° = 180°.

x + 120° = 180°.

x= 180° - 120°

x= 60°

then in the triangle whose angles were

sum of the angles in triangle= 180°

A°+20°+60° =180°

A° +80° = 180°

A°= 180°-80°

A°=100°

and

the angles that are adjacent in a straight base side were

  • A°=100°

sum of the adjacent angles= 180°

100°+ y° = 180°

y° = 180° -100°

y° =80°

therefore ,

  • x°=60°
  • y°=80°

For what value of k the equation X square - 6 x minus 2 equals to zero has real roots​

Answer»

Answer:

SINCE ROOTS are real therefore DISCRIMINANT is greater than zero.

d >  {b}^{2}  - 4ac

d >  { (- 6)}^{2}  - 4 \times 1 \times  - 2

d > 36 + 8

d > 44

Therefore, discriminant is greater than 44.
