In doing so, the instructionfinds out that 9 children arthee left out .Find the number of childran in each row of the square.24. Factories:

Answer»

Let's assume

the number of children in each row of the square is x

Since, the number of students in each row is equal to the number of rows

so, the number of children in each column of the square is x

6250 students of different schools

But 9 children are left out

so, total number of student in rows and columns =6250-9=6241

total number of student in rows and columns=(the number of children in each row of the square)*(the number of children in each column of the square)

now, we can plug values

6421=x × xx^2=6421

now, we can solve for xx=√6421 =79

So,

the number of children in each row of the square is 79...........Answer

4sin-cosB+1& 30 ९ - ८०४४०...If4 tvm 0 = 3, evaluate 4sin®+cos0-1 )

Answer»

Let theta = A4tanA=3tanA = 3/4 = P/B

In a ∆ ABC right angled at B.Base (AB) = 4 , Perpendicular( BC) = 3

AC² = AB² + BC²[By Pythagoras theorem]AC² = 4² + 3²AC² = 16 + 9 = 25AC= √25 = 5

The trigonometric ratios sin A = P/H = 3/5Cos A = B/H = 4/54sinA-cosA+1)/4sinA+cosA-1= (4×3/5 -4/5 +1) /(4×3/5 + 4/5 -1)= 12/5 - (4+5)/5 / 12/5 + (4 -5/5)= (12/5 +1/5) / (12/5 -1/5)= 13/5 / 11/5= 13/5 × 5/11 = 13/11

(4sinA-cosA+1)/(4sinA+cosA-1) = 13/11.

012.In ABCD, cyclic Quad diagonal intersect at Q. <DBC-70 and <CAB 30, so find -BCD)

Answer»

In quadrilateral

In aΔCDB andΔBAC,

∠ CDB = ∠ BAC = 30° ...(1) [ Angles in the same segment of a circle are equal ]∠ DBC = 70° ...(2)

In Δ BCD,

∠ BCD + ∠ DBC + ∠ CDB = 180° [Sum of all the angles of a triangle is 180°]⇒ ∠ BCD + 70° + 30° = 180° [ from (1) and (2) ]

⇒ ∠ BCD +100° =180°

⇒ ∠ BCD =180° - 100°

⇒ ∠ BCD = 80°

Amount of money left was given by him to his wife=Rs. 880

=>11x/25=880=>x=2000

:. He originally had Rs.2000.

Now, amount of money received by his eldest son=Rs(x/4) =Rs. 500
